Pointers, config examples, comments, even flames, I haven't tried this but it will *probably* work # interface to lan ifconfig ed0 123.123.123.1 netmask 0xffffff00 # interface connected to router ifconfig ed1 123.123.123.2 netmask 0xffffffff route add default 123.123.123.2 ifconfig should have taken care of the route to the lan.
