Hi all
I'm using 24.10 on an RPi4 and I have several WAN interfaces attached. Internet works as long as one WAN reaches the net. However for some reason the LTE dongle is always top priority despite its interface's gateway metric being the highest.
I've already tried mwan3 by reading the guide and playing around. Long story short: my mwan3 setup was supposed to be ultra simple (no load balancing, just 3 interfaces with a set order), but my attempt was scuttled by its incompatibility with nftables.
I can't get the workaround to work because I don't know how to make it so the Firewall -> IPSet rules and the DNS+DHCP -> IPSet rules allow everything since I want my mwan3 policy to just apply to everything. I also didn't want to mess with /etc/dnsmasq.conf.
So I scrubbed mwan3 from my system and decided to sidestep it entirely. Since all interfaces work without it, just not in a set order, all I need to do is just figure out how to make the system favor/disfavor a certain interface. i.e. All I want is for the LTE interface to not be the router's first choice.
Is this possible?
Hopefully someday a simple WAN priority/failover system gets integrated into OpenWRT, especially since multiwan is plain obsolete and mwan3 looks to be headed in that direction.
