PF is probably the way to go. In particular using route-to to send traffic originating from 192.168.2.0/24 to 192.168.2.1 I'm not totally sure what your static routes even accomplish. The kernel will establish routes for directly connected networks automatically. So probably some rules of interest.... # keep jails from talking to each other block in on bge0 from 192.168.2.0/24 to 192.168.1.0/24 block in on bge1 from 192.168.1.0/24 to 192.168.2.0/24 # ignore the default route pass out route-to (bge1 192.168.2.1) from 192.168.2.0/24 to ! 192.168.2.0/24 \ keep state # redundant because of the default route # which actually does what we want pass out route-to (bge0 192.168.1.1) from 192.168.1.0/24 to ! 192.168.1.0/24 \ keep state -- Thanks, Josh Paetzel PGP: 8A48 EF36 5E9F 4EDA 5A8C 11B4 26F9 01F1 27AF AECB
