Re: ER PoE - dual WAN, port forward problem

you're missing the firewall rule that corresponds to the DNAT rule

You need to add these two rules to WAN_IN:

        rule 40 {
            action accept
            description "Accept SSH"
            destination {
                port 22
            }
            protocol tcp
        }
        rule 50 {
            action accept
            description "Accept OpenTTTD"
            destination {
                port 3979
            }
            protocol tcp
        }

SSH is likely having an issue because you don't have "sticky" enabled on the loadbalancer.

set load-balance sticky protocol enable

should do it.
