Hello,
I've exhausted my abilities in trying to get my wireguard & upnp working ever since I setup MultiWAN. I setup a Group Interface, both tier 1, load balanced & failover. Everything works fantastic, except my Wireguard & uPnP now do not function. They worked great before. I have a sense from searching and reading that there may be conflicts between traffic leaving the different interfaces that could be the cause (assuming they're related).
I created a rule for my gaming PC on LAN to go out:
Source [gaming ip] * * * Gateway [main WAN] and that is working, it's keeping it on my cable internet.
Problem is, uPnP is now broken somehow & I cannot wireguard back home. It fails at handshaking.
Does anyone have any ideas what firewall rules / nat outbounds / etc that might change for those items if you move to a MultiWAN - balanced, failover situation?
Thanks

Regarding WG:
Did TCP Dump:
Handshake comes into WAN1 (correct)
Response comes through WAN2 (WG doesn't honor, handshake fails)
Any firewall rules that could solve this? Most appropriate rule to write?
Is this solvable with a firewall rule? Or does WG interface just not care where it sends the response.
Regaring uPnP

This applies to many interfaces, not just ipv6 LL

Both of these services are tied to the WAN1 interface, yet neither seems to honor
