I don't know the exact command or syntax for manipulating route tables in FBSD (haven't had to do it yet) but you want something like this. 1. Your default route should be pointed to NIC2. If you dial up changes your route, try and figure out how to disable it if possible. If not, then write some script to run after dial up to overwrite it's changes. 2. Your work subnet(s) need to be setup to go out the dial up interface. So 0.0.0.0/0 would have gateway of NIC2 (default). If you work is 1.2.3.0/24 then you would set it to go out the dial up interface.
