OpenWRT - Configure Load Balancing with mwan3

[@davebadgley2403]

This video is awesome, I got it working the first time. Thank you very much for putting it together.

[@eduardob6080]

Great video, mate! Could you, please, provide a brief explanation of the difference between load balancing (perfectly shown in this video), bandwidth aggregation (or link bonding) and Multi Path TCP? Much appreciated!

[@VanTechCorner]

Hi, I think for the defination you can just check it out on Google. Here is a quick example: - Load Balancing: 5+5=5+5 (the connection/traffic is load-balanced across wan interfaces, according to setup - Bonding: 5+5=10 (not always like that). When it comes to combine throughput of several WAN interfaces, sometime it is called "load balancing" too. Check out the Mikrotik PCC. Another term which have more or less the same meaning is "link aggregation" - Multi Path TCP: Sorry I have no idea for now

[@mayhem0007x]

this is great, all other tutorials i have checked, set the metric 1 and 2, so the the status of wan only run 100% on the first wan. i was really confused. i think this is the right tutorial. thanks, i subscribe to your channel now. thanks

[@VanTechCorner]

Hey, this video was made long time ago. On my recent video (OpenWRT 21), you can see the load-balancing works perfectly well kzbin.info/www/bejne/ppnOoad4mayGmbs

[@jonilaw1923]

Van Tech Corner is probably the most complete OpenWRT tutorial found in KZbin. Could please do a tutorial on how to install Netdata for OpenWRT? Do u also maintain a Telegram group for discussing OpenWRT for beginners? Thanks for ur effort.

[@VanTechCorner]

Hi, thanks for the comment. This video was the first OpenWRT tutorial on the channel and now there are a lot of tutorials, feel free to check it out. To install netdata, you just need to go to Luci - Software, Update the list and search and install netdata and that is. There is a FB group, you search for "Van Tech Corner & Friends".

[@theshelby90vibes56]

Very good help my friend. I would like to know if you can do with 3 WAN ports? if so could you explain me which step further i should do? A hug and thank you very much.

[@VanTechCorner]

You just need to setup the 3rd wan interface on Network-Interfaces. After that, duplicate the configuration for the 2nd wan interface on mwan3. Load Balancing with mwan is not easy for beginner, since you want to setup for 3 WANs, this is more than what a normal user need. My advice is to read the document to understand how it works first, after that configure on your own.

Hi,my case is one is a portable lte wifi router and the other is wired broadband plugging into the ethernet wan of my openwrt router...Can i bond (LTE Wifi + Wired Wan) both for failover or combine to increase bandwidth?

[@VanTechCorner]

Yes you can. Just to create the interface name in mwan3 with the same interface name on Network - Interfaces. For example, for LTE wifi you will have an interface name "WWAN". These name is case sensitive so make sure you get it right. OpenWRT use linux routing for load balancing so the bandwidth will not bounded to gether, only the connection is load balanced. I would suggest you to go with failover mode instead of load balancing if you have Wire + LTE.

[@GETOFFMYLAN]

Can you say use mwan3 to redirect traffic for one host, say a tablet to one WAN interface?

[@VanTechCorner]

Yes this is correct, you can do this with either mwan3 (custom routing tab, need a fixed IP address) or Policy Routing (either IP or MAC address will work).

[@Zainnny94]

Nice tutorial boss... Just have some questions, If I have 2 different ISP, and if 2 different download and upload, can I use this method? And if yes, the download and upload speed will be combine using load balance ? E.g ISP-1 have 10up/5down, ISP-2 have 5up/5down combine these two using load balance method will be 15up/10down Am I correct ?

[@VanTechCorner]

Nope, mwan3 supports IP based (connection based) and only the connections will be load balanced, the link speed is not combined to gether (not session based). But still, you can setup load balance with 2 different link speed. For more detail, please see the mwan3 document where you can understand how it work (in the video description).

[@Eliastaye6]

Great job man wow! Can i load balance 3g/4g and WAN?

[@VanTechCorner]

Yes, absolutely you can do that. However, please consider setting them as failover mode instead of load balance. I would advise to load balance the connections that has the same bandwidth.

[@Eliastaye6]

@@VanTechCorner can it be used on a Tp Link tlmr3420?

[@Eliastaye6]

Oh the original firmware of my router already supports failover i want to get maximum throughout. I have adsl 3mbps and 4G which the speeds vary from 10-80mbps. Maybe the exact term I’m looking for is bandwidth bonding. With the compromise of latency i can get addtional bandwidth.

[@VanTechCorner]

Mwan3 uses Linux policy routing - it is IP based, not session based. Which means, your throughout is not bounded. If you really want this, I suggest the Mikrotik routers. You can give a try as long as the router has enough flash and RAM to the package.

[@wahyu9126]

Is possible running wireguard client & load balancing mwan3 with 2 wan? Can you make tutorial

[@VanTechCorner]

I am not really sure on this, but you can always give a try. After done with dual wan load balancing, you can install wiregoard client and see if it work. Else, you can assign the wireguard interfaces into mwan3 members instead of the WAN interfaces and see if the connection is load balanced.

You can go to Mwan3 configuration - Rules and create your own static route. The mentioned section is at 15:45

[@AdityaKumar-jj9cq]

@@VanTechCorner Can you tell me how? In the video, I don't think you have mentioned it.

[@VanTechCorner]

You need to create a new "Member" that only contains 1 inteface (which you want to configure the static route), create a Policy that only contains 1 "Member", and then go to Rule, add a new rule, you will need to fill in the source IP, destination IP, the protocol, etc and lastly on the "Policy assigned" select the "Policy" which has only 1 member that you have created.

Then you just need to fill in the source IP of the device and select the policy which has only 1 WAN interface and all the traffic from that IP will only go to the defined WAN interface.

sử dụng openvpn như 1 interface trên mwan3 thế nào bác ơi

[@VanTechCorner]

Khi quay vpn thì trong Network - Interfaces của bạn sẽ có các tunel, bạn gán metric cho nó. Sau đó, trong mwan3, bạn chỉ cần theo y hướng dẫn và thay WAN interface thành tên của các tunel là xong.

@@VanTechCorner cảm ơn bạn, để mình thử. Mình chơi Openwrt từ năm 2014 tới giờ mà không tiến bộ nổi do không có kiến thức chuyên sâu về mạng. Mình chỉ vọc vạch compile openwrt cho từng loại router, và mod flash với RAM cho router thôi. Về config mấy cái chuyên sâu mình bó tay.

Tức là bạn đã có 1 đường truyền WAN/ VPN tunel có thể vào được các trang bị chặn? Nếu vậy thì bạn tạo riêng memeber, policy chỉ chứa mỗi interface đó và vào mục Rule của mwan3 tạo static route cho nó, để mọi traffic (hoặc bạn có thể custom protocol, source IP, destination IP, etc) chỉ đi vào interface / tunel đó.

[@DrHarryT]

I could see the traffic is much greater on WAN as if WANB was not being used to handle balancing for the different sites bandwidth. I have the same configuration only two 6Mb/s connections. on one computer I can download a test file and, on another computer, run a 4k YT video. This is more than enough to utilize all the bandwidth of both connections. It will utilize ONLY one connection at a time and I never get more than 6Mb/s on both devices COMBINED [3Mb/s + 3Mb/s] even though I have 12Mb/s combined capacity on both internets. Load balancer will only use on connection at a time with multiple devices connected. When one almost catches up it switches over to the other connection and keeps switching back and forth between the two connections never using both at the same time. I can be downloading Windows from Microsoft and my daughter turn on the TV to watch a Netflix movie and she gets the constant buffering circle. The load balancer refuses to use the second connection to give her a good internet experience which is the whole purpose of having load balancing with two WAN connections. What is the configuration solution that will allow me to use both internet connections with multiple devices connected to the load balancer requesting data?

[@VanTechCorner]

Hello, you can take a look at the mwan3 docs and find your answer there. openwrt.org/docs/guide-user/network/wan/multiwan/mwan3 This video was made long time ago. I have a new video for OpenWRT 21 where you can see the traffic flow to 2 WAN interfaces kzbin.info/www/bejne/ppnOoad4mayGmbs

@@VanTechCorner I've been over the doc's and can't see anything to ensure that traffic from a new device request is automatically sent down the least active connection.
