[@owolabitaofeeqowodunni8609]

TKSJa, I really hope you are fine wherever you are. For years now, you've been of great help to me through your videos. Thanks a lot!

[@TKSJa]

I appreciate that, thanks!

[@SaidulHassan]

Watched 35+ of your videos on MikroTik in a single sitting. Planning to purchase RB3011 for my workplace and now I know who to reach out to should I get stuck! Only video channel in English language that speaks on MicroTik configuration and sounds like poetry :-) Thank you @TKSJa

[@Joshv918]

Ive been watching 100s of these and this is the first one that helped.. thank you !!

[@gpligor]

Could you update this video into a longer video explaining why you are taking the steps you are taking ? This is advanced configuration and certainly not self explanatory or intuitive. Many thanks

[@arunkhan4951]

.Agree, an explanation of the "mangle" table entries would be very helpful

[@terexshop6795]

thank you!!!(i'm zero knowledge in mikrotik) it simplify my work! ...watched from tutorial 1

[@tim6053]

Ok, so after the last comments, I started from square-one. To get the best results, it is preferable to do a "reset-configuration" prior to starting the process of the "Load Balancing" exercise. In my case, I had been using the router for other things, and a lot of little settings had been changed causing (I suspect), unpredictable results. I also had saved, and exported the configuration settings to a file so I could paste them in one at a time to ensure I could see what was happening. So, after doing all that, it now seems to work perfectly.. :-) :-) Thanks !!

[@TKSJa]

+Tim Great!

[@jasonminae]

Thank you for being a blessing to many. Be mightily blessed for sharing this valuable knowledge on how to configure the MikroTik routers.

[@TKSJa]

It was a pleasure, thank you

[@Paulosantana2k]

This method only works when the cable is unplugged or the interface is down, but it doesn't when the route is unreachable.

[@netsurf_technologies]

am so greatful.your tutorials have helped me build my own local isp network in my area

[@johnbeardmore8190]

TKSJa, I really enjoy your tutorials, but I'm too dumb to implement your scripting. I want to do something akin to load-balancing with unequal ISP's. I have a 5-port MikroTik hAPac2 router. Is it possible to purchase or otherwise attain a RouterOS pre-configured and 'plug & play' that I can just change the relevant IP (interface) values to match my needs? Thanks (John)

[@HussainAkbar]

Great tutorial. Succinct and to the point. I've got two out of three of my connections shifted to the router and working fine in load balancing mode.

[@frostsmaker8966]

This is what I requested,.. I'm so happy. Now I can set it on my router.

[@guska_10]

thx for your channel,, i hope be will learn more about mikrotik... SALAM DARI LOMBOK INDONESIA

[@vincekimcostales6658]

It works on my requirement! Highly recommended! Thanks!

[@georgegithu9913]

Thanks TKSJa, your videos are very useful in understanding mikrotik in depth, i have one issue when my two ISP are live the load balancing is ok, but when wan2 i running then and wan1 is off internet works well but when i reconnect Wan1 back while wan2 is still working the internet disconnect until i disconnect wan2 and reconnect it again.

[@nziokaaustin]

Set the distance in both routes to 1 for both connections and change check gateway from ping to arp.

[@rizwanjamil7884]

I have two connections one with 15Mbps and other 30Mbps. I want an output connection of 45Mbps along with fail over

[@kqabro]

Hi TKSJa Thanks for this informative and valuable guide. As the gateway add is local ip add of internet connected device, what if the internet is down, but your connectivity with that device is up, as ping will still be alive? further for 3 WAN connections, will be the per connection classifer instead of 2/0 and 2/1?

[@ericsherwin8693]

Excellent video! You helped me understand what I was doing wrong. Thank you

[@faridshahab8291]

Thanks very much, you just saved me a lot of time and headache! and also I was thinking whom should I get help from and you just did it. Thanks again. F

[@denisvyatkin9442]

Спасибо за инструкцию, все настроил, работает!

[@eduardosedotes7726]

Thank you, my friend. I have difficulty understanding the wiki documentation. This made it easier!!

[@TKSJa]

You are welcome

[@Kangreeman]

Thanks you very much. I follow every step and it works perfectly in a CCR1016-12G.

[@HarounHakeel]

Good Stuff you doing there. Quick question, Suppose i have different local subnets, i.e 172.0.0.0/28 & 192.168.0.0/24 do i create independent mangle rules for each subnet or how do i go about it?

[@slowboyzrepublic1529]

Hi sir, what is the configuration of bridge in this tutorial. thanks

[@chasqui87]

Hi! I hope you are still active. Ty for your video it worked perfectly. But when I download something I can only have like 25% of the total with some spikes of 100% from time to time. Any advice?

[@karoldiestra8746]

Thank you very much for everything, I would like to know if you could create a tutorial to separate traffic for 2 wan for example navigation by WAN 1 and games for WAN 2 since I have seen many tutorials and I am confused and nobody better than you to clarify everything

[@vencislavvidov]

thanks, I think one thing is missing, starting point. we start from somewhere, but is not clear where. it will be nice if we load or reset some default configuration.

[@amilcarjauregui1023]

Thank you very Much!! Everything I know from RouterOS comes from your turotials and my network is running flawessly.

[@SyakirIshak]

How about SSL connections? Will it be sticky with just these config? My concern is my LAN user are accessing, say online banking. Will the https terminated/flap due to change of public IP? Thanks for the great video!

[@JankyVzla]

You could do some video explaining, the best script to apply for dynamic gateways .. And the calculation that should be applied to determine how many connections should go for each WAN ... I would appreciate your help, your videos are incredible.

[@oliverregal]

would this work if the 2 upstream links doesn't have the same bandwidth capacity? How would the router know that link 1 is congested?

[@mansonchile84]

muchas gracias funciona excelente. la wan1 la ocupo con starlink y la wan dos con una linea dedicada..

[@ebrimajatta2227]

Great tutorial, Thank you so much

[@altatensioneip]

Great tutorial my friend. I have a question for you: this configuration works (I try with wan ADSL and wan LTE with Dongle) but with a limit: if router on wan1 is reachable but without connection I have no switch on second wan. If distance is 1 and 1 all works but if I have to do a failover with difference distance (in case LTE I have to use it only in emergency case) doesnt'work.

[@zanna.241]

HI, is it possible to make a dual wan connection using an ethernet interface and the LTE interface via usb port, on RB hap?

[@billhickswasgreat3421]

I frickin' love this channel!

[@tsikokwinda9940]

can any one please offer a one on one session on this topic? i got the gist of it but just need more clarity on a few things.

[@thulasidharansankaranaraya639]

I had done everything correct. Download is load balancing but upload flows in single WAN not on both

[@paulturner9444]

I am new to Mikrotik. Do you just add these steps on top of the default configuration Mikrotik provides for Home AP devices?

[@scaginivanua]

Great video, thanks.

[@francuaito]

Hi Sir, thank you so much for this usefull video, it helped me to setup a mikrotik and it goes perfectly!

[@lightbeam6783]

Thank you for the tutorial TKSJa!! Great video!! Please can you make a load balancing and failover on Mikrotik OS 7 . Like on OS 7 you cannot select invert on local connection when creating the mangle rules :(

[@keshanwilliams8220]

Can I load balance more than 2 WAN connections with a Mikrotik Router?

[@matrix-path-of-neo]

yes

[@carlb641]

What exactly does the numerator and denominator mean for the PCC setting? I saw some videos putting more rules if you have unequal WAN speeds. I thought it was the actual interface #.

[@ramonertze3854]

Hi TKSJa, are you aware of any issues of this not working with the latest versions of Firmware (6.44.6)? I follow every step you do here, but I don't get access to the internet in any of the WAN ports.

[@swapnastudio356]

Need Dual Wan. Pppoe load balancing video.

[@SavannahTL]

Is this still valid for current ROS 6.48.3? Would you change anything from this video since it's about 4 years old?

[@newtonmuuo1659]

Does this use load balancing so both of your connections will be used or does it use one connection and the other as a backup?

[@jeleeladebisi9356]

Is there a solution for a MikroTik setup experiencing issues with hotspot ports when both ISPs are connected for load balancing and failover, yet functioning properly when one ISP is disconnected? The LAN-configured ports are working fine on both ISPs. Thanks

[@maxit0x]

Hello. If my internet have a dinamic ip address i set add default route?

[@JankyVzla]

You really are the best ... And if for example, the two connections are dynamic. It would take some script to check if the Gateway switches to automatically put it without losing connection. Could you explain what would be the best script ... The two connections you are using are the same speed? For example if I have two connections of different speeds, I would use the pcc 2/0 and 2/1 or I must make the calculation to determine how many connections I want for each WAN .. I wait for your prompt response and apologize for my bad english.

[@frostsmaker8966]

As for if it's dynamic, you can use router to create static IP from dynamic IP, and then connect the router to routerboard (mikrotik). And for load balancing, there is no setting for the number of connections. It will automatically looking for different interface connection if the other one is full, or busy. Load balancing is like parallel in a battery set up. It give the same speed, but more stable without any problem, you can use 2 different ISP to provide the best stable connection.

[@JankyVzla]

I have been applying a script to avoid using a router. But I would like to know what would be the best script if we have dynamic addresses (without router) ... My other question is: For example: I have two wan: one of 8MB and the other of 2MB .. I understand according to the video and your comment that they are only needed; Two rules of pcc; Is that correct? I have seen a calculation that applies to know exactly how many connections should be used to make an accurate balance: Example: 1 WAN1: 8MB WAN2: 2MB Total: 10MB It divides: the speed of WAN1 between the total of mb: 10mbps (for this example) and multiplies * 100 WAN1 = 8/10 = 0.80% * 100 = 80% WAN2 = 2/10 = 0.20% * 100 = 20% This means that 80% of the connections should go by the wan1 and the rest by the wan2 Then determine how many groups for each connection (multiply the group of connections that are desired between the number of connections that must go for each wan) must obtain a whole number WAN1 = 5 Conn * 80% = 4 WAN2 = 5 Conn * 20% = 1 Therefore it is determined that 4 rules must be obtained in the mangle for the wan1 and only 1 connection for the wan 2 It would be correct to do it this way ... Thanks for your comments ...

[@frostsmaker8966]

Yeah your welcome. If your WAN1 is 8 mbps, and WAN2 is 2 mbps this means your highest speed is 8 mbps, you didn't get the speed of 10 mbps but 8+2 mbps. you will get bandwidth equal to 10 mbps. You can set more than 2 wan on routerboard, so I don't think you should create rule in mangle for the number of connection as for it will automatically distribute a balance connection. I have a question : 1. I want to attach a web server (Local Server) for my wireless network in ether4 (IP : 192.168.144.2). 2. I want when they type : www.juicyjust.com, they will be directed to the intended IP (192.168.144.2). 3. How to make the user go to my website instead of other real site (global website)? I had did my research, but I'm not sure. This is the script : ======================================================= ip dns static> add name=www.juicyjust.com address=192.168.144.2 ======================================================= Will this work just with that? Please help me.

[@frostsmaker8966]

You can set a PCC rules for that, add chain=prerouting dst-address-type=!local in-interface=Local per-connection-classifier=both-addresses-and-ports:2/1 action=mark-connection new-connection-mark=WAN1_conn passthrough=yes add chain=prerouting dst-address-type=!local in-interface=Local per-connection-classifier=both-addresses-and-ports:2/1 action=mark-connection new-connection-mark=WAN1_conn passthrough=yes add chain=prerouting dst-address-type=!local in-interface=Local per-connection-classifier=both-addresses-and-ports:2/1 action=mark-connection new-connection-mark=WAN1_conn passthrough=yes add chain=prerouting dst-address-type=!local in-interface=Local per-connection-classifier=both-addresses-and-ports:2/1 action=mark-connection new-connection-mark=WAN1_conn passthrough=yes add chain=prerouting dst-address-type=!local in-interface=Local per-connection-classifier=both-addresses-and-ports:2/2 action=mark-connection new-connection-mark=WAN2_conn passthrough=yes or something like that. ▼

[@ghulamali2744]

Hi brother

[@firdousbahar4545]

Hello dear sir we live in Afghanistan and follow your KZbin ، my question is about Load balancing. I have three networks that are dynamic on the ISP rout، how can I combine these three DSL networks to match the speed of the internet. I mean when. we join these three networks the speed test of internet will show one speed test .

[@kivumbidennis1575]

Hi I have 3 Internet lines and I would like to do load balancing in one mikrotik router. Can you help me configure this via any desk? Thanks

[@leiftismo2793]

this Works perfectly on my MT, I just have another problem sir, i experienced it when 1 of my ISP where down but the router are still lit or connected to MT. it lags, i cannot browse the net unless i switch off or pull out the other modem..

[@TKSJa]

Not sure this is happening, but based on my test it should fail over smoothly.

[@abdullahiidris-y7p]

Hello.. want to priorotize traffic over of a certain website over all other sites during some periods of the day.. how can we achieve this please using mikrotik?

[@mochisanga]

Hi TKSJa, This has been working perfectly on my Network which has the single subnet class C (/24) configured in a Single Bridge. Now I have another network of class B 172.16.X.X/16. I have segmented it into different VLANS. Which interface should I replace o the bridge interface in order to make sure that all the VLANs are served by this Load Balancing and Failover (since every VLAN is in its bridge)? Please assist

[@DinuBercea]

Hi! My WAN 1 is connected directly to the ISP modem (with public fixed address), WAN2 a pppoe is passed through a router. When testing by disconecting wan1 it work ok, but when I disconect wan2 it has no dns. I tried to add isp1 dns to dns menu but it still do not work...

[@DiegoMonteiroDCADSERVICIOS]

Hello, very good video! my query is: what happens if the interface does not disconnect, only that it does not receive internet? How does the router detect this? Thank you.-

[@TKSJa]

That is an issue with this config. I will do a video show other methods.

[@DiegoMonteiroDCADSERVICIOS]

okay! I would appreciate it if you make those videos, thank you very much for the prompt response.

[@matej_stepan]

Sir, thank you for this excellent video. What about, applying a bonding into this setup? Will it work? MultiWAN-MultiGW bonding. How can I ensure, that if one WAN drops, I'll not lose 50% of packets. Thank you.

[@challenger5775]

very good and clear tutorial. More videos like 2 isp with 2 routers. for example first isp is connected to router1 and second isp is connected to router2. with load balancing and fail over effect. it is possible? thanks.

[@TKSJa]

+Reden Dimaano This kind of setup would be redundant because you can achieve this by using 1 router

[@mhndsh]

thanks.. But.. the mangle rule: add chain=prerouting in-interface=WAN1 connection-mark=no-mark action=mark-connection new-connection-mark=WAN1_conn is it "prerouting" or "input"? i found it input in other tutorials...??!!

[@nabinsubedi3918]

this means you are marking download connection from wan1 port.

[@GiorgosKapelonis]

Failover works if we unlpug one of the ethernet cables, but what happens if we will not unplug ethernet but the WAN/internet will fail due to ISP problem? Failover will not work... How to succeed failover when an ISP fails?

[@leiftismo2793]

w0w, amazing tutorial. sir would it be possible to separate BROWSING and KZbin/VIDEOS like your previous tutorial in separate gaming and browsing(im not fond of gaming)

[@bugsystube]

Hola muy bueno el tuto!! Ahora si yo quisiera que una vlan salgan por una conexion y otras por otras? Se puede?

[@rodneymoore465]

here are my comment YOUR a Genius TKSJa

[@umairbhatti4433]

Sir You help me Alot thank you soo much... You are great

[@xaymianho]

Can you give me the configuration of this? When without unplug is wan bandwidth will work?

[@paulturner9444]

Also, when I turn off the add default route setting, I lose internet connection.

[@AL6S00740]

Hey can you do failover with the same subnet on both WAN ports ? and Without NAT ?

[@JohnSmith-dc6lc]

Good explanation but it would be more helpful to start from a clean slate. Your bridge was already configured, with ether2 set as master. You still get a 👍🏼 and sub tho..

[@shaktipatil]

Thank you so much for detailed video.

[@TKSJa]

You are welcome.

[@EmilzoPazDigosII]

I use ether1 and ether6 so I need your help about the PER CONNECTION CLASSIFIER when adding MANGLES for BOTH ADDRESSES for ether1 i applied same config for Both addresses : 2 / 0 so, ether6 must be :2 / 1 or : 2 / 5 ?? Thanks for your answer please !

[@sujanlimbu9997]

I had watched over 5-10 videos regarding load balancing on youtube most of them do chain-input while making mark-connection for Wan.in this video u have done chain prerouting what is the difference of doing that sir? I have configure my mikrotik router with dhcp client and ppoe client but i got confused while accepting dst-address beacause when i configure WAN1 as ppoe client it gives out address like 202.51.84.11 and network 103.10.30.4,how can i know cidr of this network so i can use it on mangle rule to accept dst-address ?please help

[@mitchellcampbell2775]

So helpful! Thank you so much!

[@vzmmmdov4045]

Hi. I need WAN2 to only kick in when WAN1 is dead. Do you have that video please?

[@sncbd1]

I want multiple connection to fail-over. In your configuration if any link goes down it will fail over but if the link is up but the ISP end has internet issue the connection does not failover. If you know how to fix this please help. Thanks in advance.

[@MohammadZaherRezaie]

if the IPs in wan ports are assigned statically how can we do load balance?

[@bricekamdemsegmino2104]

Very Good vidéo

[@veronbike]

You are the man! works perfectly! big big help!

[@sazib94]

Hello Sir, In my mikrotik, i can't find master port... So how do I solve this problem, wait for your reply

[@conradwawire]

same here

[@arvindersingh4564]

very nice bro.

[@kdeclinetostatendeclinetos6707]

Yes that is easy, when you assume that your gateway goes down when internet goes down. It is rare case scenario. Usually gateway is fine and failure is somewhere in the operators network. This is most simple and not practical sample.

[@Anonymousinfatuation]

Thank you. I need a script of 6 WANs load balancing. Can you do that for me? From Pk

[@winstonscentraltechnology4238]

Is it possible to add 2 wan and let specific devices pulls data from a specific wan at all times?

[@MhNetSecurity]

Imagine that the interface ISP1 is up but Internet line is DOWN through that line , the clients passing through it will not reach the Internet.you need to configure the recursive route in this case , yes ?

[@dmsupport6423]

Can U Share 1 public ip on 2 Line ....Without nat in Mikrotik

[@Anavllama]

What is the purpose of the two first rules................?? I dont see the value or use for them/

[@fahad.muslimtv]

it only works when you unplug WAN's or turnoff the WAN routers, there should b a way in which it automatically convert to other WAN without unplug WAN

[@patlalande3977]

Can you do a simple bonding between 2 pppoe (wan) connections??

[@miroslavmk1986]

Which DNS settings to use and whether everything is the same if one WAN is a PPPoE client, and so ip route Gateway is set to dinamic ip, wil not work after cange client ip?

[@collinvibess417]

I would like some help with my mikrotik router can I get some help from you

[@kylepretorius9696]

Good day, thank you for the tutorial however I see if i torrent the speeds are fine however if i open a webpage or try a speed test it suffers not sure if ive done something wrong. Also is it possible to create 4 WAN Links?

[@prank-patrol267]

my router doesnt have the mater port option, what should i do

[@knowledgeseekerr]

Hey TKSJa, thank you for your helpful videos. This has been helping me a lot in understanding Mikrotik Routers. I have a question, When you set this load balance up, you use the DHCP Client to get an address from both ISP/Clients/Routers. Do you have to use the DHCP Client? couldn't you just set it up with out the DHCP Client?

[@arunkhan4951]

In this tutorial, the MikroTik router is connected to 2 ISP modems/routers. These devices give out DHCP addresses on their respective "LAN" ports. This is the most common scenario.

[@ghmc]

Unfortunately does not work with and lte and eth interface. The eth interface will not connect outside

[@DinuBercea]

Wonderful demonstration. But I have a bit different situation (router.os 6.43.8). I have already configured a connection using pppoe on ether1. How can I make ether2 a WAN port while no master port settings are available. Then should I use pppoe-out interface instead of WAN1(ether1) in load balancing configurations? (the second Internet has an fixed IP from ISP)

[@TKSJa]

Load balancing and pppoe is a bit tricky. It's better to configure another router for load balancing only.

[@junarellano7115]

hello , is this kind of configuration also applicable for static setup?

[@laszloperesztegi]

Yes, it works for static gateways too. Btw. its not elegant that he switches off the DHCP-client service, because in case the IP address of any gateway changes then his users will lose Internet and you have to visit the router on site.

[@mohammedibrahimkhan3773]

fine video

[@forex-chart-analysis-daily]

i have 100mb and another 50mb plan when i do load balancing my client cant use proper internet always internet slow when i closed one wan port then internet is very fast how i can solve this problem
