Multiwan settings per device

[AppleMan]

Hello,

I am using a Flint2 router with the default GL.iNet firmware.

I am wondering if it's possible to setup rules for multiwan per deivce. I am using two differnt internet connections. I have set my Multi-Wan settings to failover and my Ethernet 2 as first priority and Ethernet 1 as second. This works great on my devices but I would like to assing my Homeserver to Ethernet 1 specifc.

I already tried installing the luci-mwan3 package as this seems to have more options but it seems like the original GL.iNet provided Multi-Wan does not really play well with the LuCi package.

I don't really see where to start at to be honest. Does this even work with the default mwan3 package provided?

I think I figured it out and was able to setup the mwan3 interfaces as I would like. But in the process I somehow "destroyed" my IPv6 connectivity and I don't get why.

This is how my /etc/config/network looks like:

Everything looks fine so far and IPv4 is working. But I cannot reach any IPv6 destination from any device apart from the router itself. So this might be a firewall issue? As soon as I disable and enable IPv6 via the Gl-Inet interface IPv6 will work for a few seconds.

In LuCi I always see the error " WARNING: Interface wan6 has no default route in the main routing table" and " WARNING: Interface secondwan6 has no default route in the main routing table" in the mwan3 app.

Checking the my routing table:

Probably there is plugins conflict in gl-kmwan and mwan3.

If you require to use the mwan3 to manage the Multi-WAN, perhaps recommend installing the vanilla OpenWRT firmware.
