[@punch3n3ergy37]

Nice video! If i use this on my Raspberrypi, does it need to be the "router" of my home network so that other devices can benefit from this connection? I'd be quite interested in the wireguard option since i am already running some wireguard connections to a VPS.

[@vincentrabha5580]

Hi Marc! Your tutorial is a great rescue for me.... I came accross your internet bonding tutorial after going though a lot of hoax and fake tutorials on youtube. I live in a village in India where we have no broadband or high speed internet connectivity... but only slow speed connections over mobile broadband which hardly goes up tp 1 MBPS. I saw your tutorial was unique and gave it a try and ..... I finally could bond 3 mobile internet connections using a VPS based in Mumbai, in India..after a series of failed attempts... I was surprised to see the internet speed shoot up to 24 MBPS on Raspberry pi which I never expected..... the speed is even more than what I received when I used speedify whose nearest VPN is based in Singapore. Thanks a lot....!!!!!!!!!! Your tutorial is a saviour for me. I have successfully forwarded the bonded connection over ethernet port of Rpi and able to use it on windows and mac....I'd like to try more of your tutorials. .... My heartfelt gratitude for these genuine tutorials.... they're awesome....

Hi Marc! I'm quite late to this video, but as a non-techy, this is the exact solution that I (and many others) are looking for! There's a huge market out there for livestreamers that need a mobile bonding solution. Most companies that offer something like that charge up to $2000 for a solution, but after watching your video, it seems absolutely doable with some time and a raspberry pi. If you are still taking requests, I would love to see you create option 4 (custom build) that can bond multiple mobile connections into a portable bonding solution! Thank you so much for this great video and looking forward to seeing what you come up with!

I hope that your video explains the set up process in a less daunting manner! Thank you again Marc!

I'd love to hear this continue in the openWRT realm, for its broad hardwares support, from home router, to Raspberry Pi, and even x86. I have a tragic life being a networking geek living less than a kilometer away from big ISP's distribution station, but my area is just out of their wired internet coverage. So I keep my 2 x 1.5 Mbps LTE connections.

[@OneMarcFifty]

Ah - that‘s really mean! Living next to the node and not getting in! It‘s been like this at my place for years as well- all the neighbors enjoyed high speed internet and I was on a slow line - I feel your pain 😉

[@Jamie]

This is awesome! I could see a lot of practical uses for such tech, so definitely keep working on it if you can! A twist on this that I think would be really good would be a configuration that allows multipath transmission, to try and get a reliable connection if one of the connections isn't very stable (without incurring much packet loss).

[@OneMarcFifty]

Fantastic feedback, many thanks Jamie. Its definitely on the list- The bonding strategy is something we will look at in the 3rd episode

This is really interesting. With either wireguard or OpenVPN. Wireguard is supposed to be much faster and newer however OpenVPN still has more support and is able to handle user authentication.

[@MyMasterjee]

I got so excited when I stumbled upon this video. For the same reason, I wanted to set up something like this for my parents. I am a technical guy with 25+ plus on the software side but never had a chance to explorer networking. I spend my few weekends trying to test and configure my Raspberry Pi 4 with two WAN connections (two mobile phones, ATT and Verizon in USA, connected through USB port) and an aws ec2 instance as a VPN server. Bottomline - simply, it doesn't give you the expected result. Technically VPN over the bonded interface works as suggested by you, but it does not increase the speed. Here is my configuration: Location - Bay Area, USA WAN 1 - ATT cell giving me 60+ Mbps WAN 2 - Verizon cell giving me 60+ Mbps VPN Server - Amazon EC2 instance with 8 core and 12gb RAM hosted in N.California region. Ubuntu Server. VPN Client (No encryption) - Rasberry Pi 4B with WAN1 and WAN2 connected through USB tethering. It's located very close to VPN server and getting 120+ Mbps without over my DSL connection. Moment of truth - with VPN over bonded interface, my speed dropped to around 40 Mbps. Well - I was expecting 60 + 60 = 120Mbps. Actually, I turned on monitoring on both USB interface and VPN Server tap interfaces - to my surprise, they are sending and receiving traffic, but the speed drops instead of combining. Speed Over simple VPN with encryption - I am getting 60+ Mbps, so it's not the speed between two VPN endpoints or the cell network. Theoretically, I still believe in this solution, but just didn't work in my environment. On the hindside, I learned a lot about networking. I am offering anyone who can help me to build a reliable solution that I can use to see my parents every day. Thanks a lot for sharing this video!! Script I was using to troubleshoot. !/bin/bash echo "-------------------------START---openvpn---------------------------------------" systemctl list-unit-files | grep -i openvpn echo "-------------------------------------------------------------------" systemctl --type=service | grep -i openvpn echo "-------------------------------------------------------------------" ps -ef | grep -i openvpn echo "-------------------------Networkd Interface------------------------------------------" ip -br addr echo "-------------------------------------------------------------------" ip -br link echo "-------------------------------------------------------------------" OUR_OWN_IP=`sudo -u nobody curl -s ipinfo.io/ip` OUR_OWN_IP2=$(grep -m 1 -oE '^[0-9]{1,3}(\.[0-9]{1,3}){3}$'

My use case for it is just to connect my private NAS / VPS server locally to my main machine over two links directly between the two systems. I had an idea of how it as done and knew it required VPN bonding as normal link aggregation is not enouph. I do thank you for the video and will review the scripts. I am not sure of exactly what commands to issue to setup openvpn in this way, however I should be able to setup multiple instances of open vpn on VPS server.

[@OneMarcFifty]

[@utopianit]

Thanks for your video Marc. I've been interested and involved in commercial internet bonding and networking solutions for years and have deployed various solutions for enterprise clients using technology from Viprinet and Mushroom Networks. I was looking at Speedify for home office broadband bonding, but being a network engineer and IT generalist myself, the idea of a linux based solution caught my interest. Given the speed improvements of Wireguard over OpenVPN, I'd definitely recommend looking at that as there's less packet overhead an demonstrable bandwidth improvements. If the TUN interfaces can support this then it could definitely work. Admittedly I haven't looked at your Git repo yet, but plan to shortly. The problems with using Raspberry Pi's is of course the number of NICs and even a Pi4 with a USB ethernet adapter or multiple LTE/WiFi dongles, it's not overly graceful. I was looking at using a (refurbished) HP T730 Thin Client for this sort of thing personally with a half-height quad port NIC. These are often used for pfsense/opnsense and could work nicely with this. Have you looked at using a VPS from providers like DigitalOcean or Upcloud as that's potentially the route I'd take for this?

[@OneMarcFifty]

Hi Chris, awesome feedback, many thanks. As far as my investigations go for the moment it will be difficult to bond wireguard interfaces directly, I am currently examining the possibility to use some sort of tunel with weak encryption, maybe over a tun VPN. I agree, Raspberry Pis are not necessarily the easiest to play with, given the Ethernet limitations. One could easily overcome the number of NICs by adding a managed swith and enabling VLANs, i.e. "map" the VLANs out to the physical ports on a switch. But then if you count the price for the Pi plus the switch plus the dongles you will have to spend 200+ USD for an OK solution. I need to test performance on a mid range easy to purchase ready made router like the Archer C7 - of course a thin client PC would probably be easiest. I have also looked at Virtualization options such as virtualbox (i.e. run the router in a VM) - maybe I'll do some distinct videos on each subject ( we are approaching the 1000 subscribers milestone, so I want to make something special anyhow). I haven't had a look at the providers you mention but will do.

[@huseyinozsut9949]

USB 3.0 1000mbit nics are pretty cheap. You can buy two, hook it up to raspberry pi and get three ethernet connections if that works. The problem is, usb ports and ethernet port share bandwith in raspberry. In theory with 3 nics in total you should be allright. And 4 nics would be the limit. ------- I am searching bandwith bonding to increase my truenas server's remote connection capability. In Turkey download speeds are ok. 100mbit/s. But upload speeds are 5mbit/s. With paying extra, it increases to 10mbit/s. To work with a disk server remotely, 10mbit is pretty slow. So I will try to combine two 10mbit upload speeds if possible.

[@mohrerao]

Great video. Thanks for explaining it in detail along with ready to install scripts. I was able to set it up on my pi4 and get going. However, couldn't achieve the desired results as there is lot of latency. It would have been great if there was an uninstall script so that we can revert all changes if not needed.

Hi Pedro, I have not really followed up with this project any more - you might want to have a look at OpenMPTCPRouter instead ;-)

[@richardbrooks121]

This is something I need. I have two LTE G4 wireless connections in our small rural town - both "unlimited data", but one uses traffic management so it slows down at peak times (which is pretty much any time of the day or night - I actually think the provider has oversubscribed the service). Anyway, I've tried a Unifi EdgerouterX which supports channel bonding, but the engineers tell me it won't work unless I'm dealing with two connections from the same ISP. I've also tried Speedify but after seeing under the hood how it works, I'm not particularly impressed. I'd rather build a system using Raspberry Pi or OpenWRT, or even hosted VPS. Doesn't really matter how, it just needs to increase my speed.

[@OneMarcFifty]

Hi Richard - this solution needs two similar lines really. What you get is twice the speed of the slowest line. Alternatively you might want to check out OpenMPTCPRouter for this.

[@Tikmysta]

Thanks for sharing and explaining. Definitely what I am looking for but my technical knowledge to implement under a fairly tight budget and strict timeline might be a shortfall for my immediate needs.

[@MrZeynelyenici]

It might be worth taking a look at mikrotik. they offer cloudhosted routers (I have a few running at hetzer vps myself). and the hardware routers, start at 30€. it can do bonding, openvpn, wireguard (in 7.0 beta4), and everything firewall, NAT, mangle roules you can imagine. And I think it's a great management app. Thank you for the great video, it gave new impulses for new Ideas :) Forget what I said, I just saw your OpenMPTCP router video. ^^

[@OneMarcFifty]

Hey, many thanks for your feedback - actually, yes - OpenMPTCPRouter is one solution, nevertheless - I have bought one of the Mikrotik Routerboards and I am actually very pleased with the completeness of their Software. However, where things become tricky is when you need to troubleshoot or use additional software - this is where an open system running linux just eats them all - My plan with that Routerboard (plus I bought a Bananapi R64) is actually to build my own 4G Auto-Failover-Router ;-) Stay tuned ;-)

[@botvisible3887]

Hi Marc, late to find this out but it is a great tip and trick. I am already implementing it. My next suggestion instead would be to how to enable port forward on the vps so that certain ports can be forwarded to the home device. I am sure it is a matter of few commands but just mentioning. Then I feel this will become a “cloud home router” solution.

[@OneMarcFifty]

Hey, great feedback and idea, thank you

[@bizanator8558]

Good work, I worked on an open-source wifi project several years ago and had built it off RasperberryPi with a solar charger and USB battery bank. The concept was to provide wifi security awareness with a 4g card and phishing wifi, this was before EvilIP scripts. That being said I've wanted to revisit it again as I had started building a spider box to combine multiple wifi connections into one but at that time OpenVPN bonding was not working, I'm very impressed with your progress. I would be interested in seeing your custom build, based on OpenWRT or Ubuntu or Pi. These all are offered in ARM/x86 versions so I would think it doesn't really matter. To make it reliable or usable in rural areas resiliency would have to be built it, in many environments cell signals are very very poor and drop constantly but bonding with self-healing would provide a viable solution. I'll reach out to you on Reddit and we can go into more details.

[@OneMarcFifty]

@OneMarcFifty,, could you consider WAN Bonding with ROOter and OpenMPTCProuter? ROOter is very well built for cellular/wisp usecase (failover for when wired internet backhaul might die or overloaded). For example, with everyone working from home, everyone is using the wired internet backhaul that was not planned by backhaul engineering when the lines were laid. Using a cellular bond that might connect to a separate backhaul miles away might help address congestion.

I'm for options 4 and 3 immediately since i already have the hardware - looking forward to following future videos from you @OneMarcFifty although I know I'm coming to this late (byline says "3 years ago" as I make this comment) the equipment is in fact vintage, so it will come down to a matter of firmware version availability at this point (2023) or so I would imagine going in

[@KazenoniKakuremi]

This was awesome, please definitely do a follow-up explaining if software defined adapters can be bonded I have a totally different problem, i have a super high speed connection 100MB. However, when i use OpenVPN i get 8MBs down and 35 MBS up

[@OneMarcFifty]

Hi Harri, this can have multiple causes. Typically even if you have 100 or 1000 Mbps at home that says nothig about the effective speed between your place and the VPN server as the packets need to go through various bottle necks. In order to figure this out, you might launch iperf over ssh on your vserver and measure the speed. Are you using your own vps server or are you paying a service for this ?

[@subhobroto]

@@OneMarcFifty One question I would ask Harri is if they have AES-NI enabled processor (I only use Intel. AMD might have similar) on the machine that runs OpenVPN.

[@gordslater]

Another awesome vid, both technically and very clear presentation - thanks I vote for (2) Wireguard, and (3) OpenWRT with Wireguard (because a lot of router hardware is very slow with OpenVPN due to weak single-core performance) Also, (5) some Resiliency may be a good idea, especially for rural locations with elderly parents haha Even a couple of lines of pinging to make sure a tunnel is still up with sane latency would be a help My thoughts ~against~ a specific hardware project - this takes up your time as you mix/match/troubleshoot the hardware over and above the coding. Personally I'd rather go generic, specifically on OpenWRT client routers as my prefence, though Debian at both ends is fine, it just requires more costly hardware (than OpenWRT on ex-CPE hardware for example) It MAY however be goood for your channel to offer a simple Raspberry Pi project version, at least in simple form, because it is a popular platform especially for beginners. OpenWRT geeks are geeks already, but Raspberry Pi users tend to actively search out projects and solutions for fun. I've found it's very easy to get bogged down with battery backup/UPS issues when in many cases if you lose power, you just do something else until it comes back on, especially if it's just a family chat :) I also prefer a spare duplicate microSD card - just a simple dd - to a UPS for Raspberry Pis in case of power failure. Finally, to help limit bandwith using simple non-tech measures in video calling, we've found the following can work well :- Always start with a voice call to explain what to do -and arrange to hang up video and go back to voice call if it's not viable. + Discuss who will make the decision to hang up and redial if so (best for the techie to do it) Make sure both ends place their fones on a stable table and don't use them handheld (less camera movement, compression is easier + less glitchy) Have a simple evenly-illuminated background, like a plain white wall, at both ends Don't sit too close to the fone, so the head and body doesn't fill the screen (you move as you speak, but the wall doesn't, so less bandwidth) Use earphones at both ends to prevent audio echo problems (very confusing for elderly people and also, it's extra packets in each direction) Upstairs - you want good signal if using mobile data Try to have a nice quiet evironment with no movement - avoid stitting with your back to a main road or television or busy bar ! Set quality to minimum if this is an option, or maybe try dim lighting (yes - really!) which can sometimes force lower camera resolution on some phones.

[@OneMarcFifty]

Hi Gord, many thanks for your thorough feed-back. I do agree, there are a couple of simple things that can be done in order to make this concept usable for the broader audience, such as adding stuff to ip up/down scripts, check latency and possibly fall back/forth automatically.

[@OneMarcFifty]

Hi Vedran. Packet reordering _is_ an issue with this solution, i.e. it only works with lines of approx. the same speed. The reason is that you can't use the different load-balancing algorithms because ethtool gives back a hard coded speed of 10 Mbps for VPN interfaces...

Sehr kompliziert. Das einzige, warum ich dies als plausibel erachten würde ist der layer 2 Aspekt. Denn mit dem layer 2 benutze ich Ethernet over IP, um das Fehlen des VLANs zu umgehen. Weil die Trottel von AVM, trotz ihres Preisniveaus, immer noch nicht VLAN in die Fritzbox gebracht haben. Auf Layer 2 zurück, kannst du vielleicht näher erläutern, wie das mit dem data-link layer meine Verbindung schneller macht? Mit diagrammen wär toll. Meine letzte Meile kann 100Mbit/s und beziehe 25Mbit/s Internetverbindung. 2 Adern (nicht relevant), bedarf Synchronisierung, wie bei VDSL üblich. Kriege ich also aus meinem Internetgateway mehr Geschwindigkeit durch einen Layer 2 (Data-Link layer) Trick? Und muss ich jeweils was beim MTU- bzw. L2-MTU-Wert beachten?

Hi, quit good video on the topic. But what about ppp. If you want to leave out the encryption maybe another soltion is gre tunnel with pppoe. With this the ppp can Bundle both interfaces together. Which in hinsight could be better soltion for "small" router with openwrt on it.

Hi, many thanks for your comment - and thank you for liking and subscribing - Awesome ;-) in fact for dual WAN you could easily use any router that can run OpenWrt and configure VLANs - I do however not know about a specific router with 3 NICs - Now I am a bit sceptical with regards to bonding 2 FTTC connections in order to get to high speed because you would need to find a VPS that you can reach at that speed... The idea of the solution was rather to provide better speed at rural areas with 4-10 MBit etc. ;-)

[@shashankmanerikar]

interesting , Thanks for video, we would really want to know about how bonding algorithm is working? what about overheads?

[@OneMarcFifty]

Many thanks for your reply, we will have a closer look at the technical details in the next episode, however we will focus more on routes, rules and tables. The algorithm as such can be changed by adapting the value in /proc/net/bonding/bond0 (see www.tecmint.com/network-nic-bonding-teaming-in-debian-linux/2/ for explanation). The overhead is basically the normal VPN overhead, plus serialization for bonding plus encryption. So depending on how you encrypt and how low your MTU is it can become quite high. I haven't measured it in detail, but I'd estimate 10-20%.

[@OneMarcFifty]

IN ORDER TO CHANGE THE BONDING MODE USE THIS: /etc/openvpn/stopbond.sh && ip link add bond0 type bond && echo 5 > /sys/class/net/bond0/bonding/mode && /etc/openvpn/startbond.sh && cat /proc/net/bonding/bond0 (change 5 to any pf these values : mode=0 (Balance Round Robin) mode=1 (Active backup) mode=2 (Balance XOR) mode=3 (Broadcast) mode=4 (802.3ad) mode=5 (Balance TLB) mode=6 (Balance ALB)

Hey Martin, your timing is perfect - I am currently looking into Multipath TCP and building a test lab for it - in essence, there is a solution called OpenMPTCPRouter that uses Multipath TCP and can be set up quite easily.

Knowing that MPTCP is implemented with Ubuntu 22.04, is it better to use openvpn with MPTCP or openvpn with bonding? I would like to use 2 flaky connections at the same time. Thanks. WireGuard with MPTCP doesn't seem to be an option, since WireGuard uses UDP.

Hi Jerome, on a general note MPTCP performs better if you have asymmetric connections. The here suggested solution works good on (slow) symmetric lines as there is no packet reordering or the like.

Now the VPN bonding as I suggest in the video should really be lookad at as a Proof of concept rather than something that can be deployed on a larger scale. It has limitations in the sense that it does not do packet management etc. - OpenMPTCPRouter does this. Where VPN bonding works well is if you have multiple lines with the same speed an comparable latency. If not, use OMR.

@@abhishekgurumath862 Sorry my reply took so long - I have somehow not been notified of your comment.The troubleshooting steps would be as follows : 1. Try to see if you can ping the VPN address of the VPS Server (10.8.0.254) - does that work ? If not, the VPN is not established and/or bonded correctly. Next step, do a traceroute to a server with known IP address (e.g. 8.8.8.8 or 1.1.1.1) and see if it works and if it goes over the VPN bond. If that works, then bonding is OK, If not, then check if ip4 forwarding has been enabled on the VPS by issuing "sysctl -p" - could be that the masquerading rules are not working neither. Next step, see if traceroute works with a host name - if it doesn't then DNS is the problem. Let me know how it goes. Sorry again for the late reply.

I was wondering if its the sam as trunking switchports. Many prosumer hardware switches can do trunk/link aggregation.... What if i have a switch at home where i have my 1Gig fiber line. Then i use 1rpi with 2 network cards as vpn server. To connect to the trunkports on my local switch... on the other end i would use 2 Hotspots that connect to the rpi-vpn at home. And use the 2 network ports of them on the „mobile“ switch. Do you think its possible? Maybe we can try it out togethe for a future video?

[@OneMarcFifty]

Hi Beni, I think this might prove to be more difficult than it looks at a first glance - I had to think this through multiple times. The issue is that we need to bridge L2 devices. In my example that is the TAP devices. Presumably the hardware switches bundle Ethernet devices (so in fact L2 of course) - however, the bond would end at the Ethernet device. You could of course bond 2 lines to the Ethernet device, then go over VPN to another Endpoint and from there pull 2 lines again. But we have a protocol Airgap that is difficult to bridge. In fact we would need to have a virtual _Ethernet_ device bridged over the VPN. I am not aware of any solution doing this. So - sorry., I think it won't work - unless someone has done anything similar please feel free to comment.
