General Discussion / Wireguard site-to-site stopped working after setting dual wan failover
« on: November 25, 2023, 09:50:21 pm »
Hi,
I started with this setup
PC A: Dual WAN failover + wireguard setup
PC B: One simple gateway (no failover) + wireguard setup
Everything worked as expected. PC A and PC B can access each other's resource via SAMBA, and PC B can even connect to PC A via RDP
I setup a dual wan failover on PC B (same setup as PC A) too, and the wireguard tunnel stopped working.
I mean, the handshake seems to be up, but devices on opnsense's LAN side can't reach devices on the other opnsense's LAN anymore, not even ping one another.
I haven't yet understood what may have been wrong.
Could you please give me an hint as a starting point, just to see where I need to check the possible misconfiguration? Thanks
for the record, here are the two tutorials I followed to setup dual wan failover and wireguard for both machine:

Thanks
