[SOLVED] Multi-WAN Broke IPSec VPN

[Adam.P]

When packets from 20 to 120 are entering enc0 device the Firewall is good. If 120 can reach 20, everything good. But when 20 can't access 120 and packets going to enc0, you'll see something in ipsec log or dropped packets.

While enabling public access to the webgui, I went ahead and updated opnsense and rebooted the 120.0 router. After the update and reboot, everything is now working properly.

I think the initial problem was that I did not have the LAN rule to route ipsec traffic via default gateway. I'm still not sure where that is documented, but thank you for sharing!

I have no clue what caused the latest one-way traffic issue, but it looks like either updating or rebooting cleared that up.

Thanks again for all of your help!
