Changing a Multi WAN Gateway Breaks Port Forwards / Firewall Rules

[jlc_is_me]

Hi all,

I have been using OPNsense for about 8 months now and love it! However I just ran into my first big problem...

I have two WAN's configured in a gateway group with failover. Gateway 1 is primary (fiber) and Gateway 2 is secondary (DSL).

I am trying to remove the router which sits between the ONU and the OPNsense machine in order to make use of additional IP address from that ISP. That part went easy enough - I simply reconfigured the interface with the proper IP and gateway from the ISP. Everything worked as it should.

The problem is with the inbound connections to the secondary gateway (DSL). I host a web server and email server from that connection. After I make the changes to primary gateway, all inbound connections to the secondary gateway timeout.

I have made several attempts but always end up with the same problem and have to restore from backup to regain inbound connectivity on the secondary gateway.

I am running version 22.7.

Any help would be greatly appreciated!

Thanks,
Josh

Sorry, I'm just returned to the land of the living and realized I posted this in the 23.1 prod version. Is it possible to move this thread to the appropriate topic?
