OpenWRT 21.02 - Multi-WAN Load Balancing with mwan3

In this video, we will configure multi-wan load balancing on OpenWRT 21.02 with LuCI. I am going to load balancing 2 WAN ports - one in DHCP client and the other WAN port will be configured in PPPoE client, on VLAN 35.
I will also show you how to configure your LAN port as a WAN port, and then create a VLAN interface on top of it.
In order to configure load balancing with mwan3, the network interfaces should have a specific gateway metric (in Network - Interfaces). And then, in mwan3, those interfaces with the same metric will be load balanced. To make it simple, we just need to assign the mwan interfaces the same metric and same weight in order to work.

Ooooh .... this is nice.

Last time I tinkered with my Linksys 1900(ACSv2 Dumb AP) and 3200 (ACM, primary) you cannot mwan ethernet ports only USB.

Thanks much!

you are skipping some parts in the process have to mention this as a newbie will get confused like I did lmao. but still very informative I managed to do the task in the end with your help

[tamodolo]

very good tutorial. Now wanb needs to be atached to a bridge otherwise it won't connect. Also I need help with UPNP that stoped working after this is configured...

Hi Van Tech Corner,

Do you have your own documentation, or documentation that goes into more detail about "OpenWRT Load Balancing with mwan3". Not only the "install / configuration" but also all the other features it has.

I'm considering putting OpenWRT on my Edgerouter X because of mwan3.

Is there a way to set-up a policy or rule to start a VPN if let's say WANB is used but no VPN if WAN?

[negocios]

Great vid, sir. Pls, how to mitigate https traffic under mwan constantly loosing connection, like corporate office365, ms dynamics and others.

Good.
BTE, what is the advantage for making ports as VLANs?

Ad ơi cho em hỏi là em tạo được 2 đường wan từ 2 đường intenet khác nhau rồi giờ em muốn tạo ra 3 mạng wifi 1 cái lấy đường wan 1 1 cái lấy đường wan 2 và cái kia thì gộp của cả 2 đường được không ạ em muốn làm vậy để backup khi mà sự cố mất 1 đường hoạt khi mình chỉ muốn sử dụng 1 đường ấy ạ mong ad trả lời ❤❤

My public IP is changes continuously. One it changes to "wan" & then it changes to "wanb"

[spinx]

Hi, van tech corner, great tutorial. I just wonder, what if the bandwidth of each port is not equal, can we still load balance it?

[shahriyarmamun]

Thanks for the video. I have two wan (2 connection from 2 different ISP) load-balanced by mwan3, how can i setup wiregurd vpn so my ip address remain same? cause in my current load-balanced scenario my public ip address change frequently. Thanks a lot

Hi any issue with internet banking if using 2 isp with LB? Afraid suddenly change to other isp during login internet banking.
