AR-750 Use LAN port as 2nd WAN? Load balancing capable?

David · July 4, 2018, 11:01am

I have three ISP at home. Can I configure 1 or 2 LAN port to work as dual or triple WAN port in AR-750? Is the AR-750 Load Balancing capable? Thx

Yes. Here is the direction you need to do.

Modify /etc/config/network

You will find eth1 is configured as lan it there is vlan configuration of the two port.

Configure eth1.1 or eth1.2 as WAN port and set it to use dhcp. Just use the same configuration as wan configure.

Set the option metric value. You must set this value so it can be tracked by mwan3. A lower value means higher priority.

Now go to luci->network-> load balance and try.

Finally have a good luck!

Thank you, alzhao ! I’ve also found some useful links to configure if someone need to have a look.

In experience to get a proper working multiple wan configuration using mwan3 starting from scratch you should:

Important: this works well on OpenWRT 15.05.1, on newer versions there was some breaking changes, for example, the wan ifaces have ipv6 capability and now are named with letters ("wan, wanb... , wanc" instead of "wan, wan2... wan3" so wanb6 means 2nd wan ipv6.): https://github.com/openwrt/packages/blob/master/net/mwan3/files/etc/config/mwan3

The official documentation seems to be very detailed and up to date, I recommend reading those first:
https://openwrt.org/docs/guide-user/network/wan/multiwan/mwan3
but I recommend to give a look at my config file below, since my approach for policyes is very nice.

First of all: Activate conntrack, docs says that is important and neccesary to get MWAN3 work properly, and it is needed to reboot:
