I think it's definitely not trunk, because of two interfaces are
connected to two different subnets, i.e. em0 is 213.x.x.x and sk1 is
85.y.y.y. They are not connected to the same switch.

Actually, after some research I think about pf.conf with proper
route-to/reply-to statements plus ifstated(8) monitoring link status and
switching pf.conf files or reloading pf tables.
