We are having trouble getting ipfw to work over a bridged interface. for example: machine 1 -> Bridged interface FreeBSD 10 -> machine 2. machine 1 - 192.168.20.20 machine 2 - 192.168.20.25 now I set something like this in /etc/ipfw.rules: $IPFWcmd add deny all from 192.168.20.20/24 to any $IPFWcmd add deny all from any to 192.168.20.20/24 where both machine 1 and machine 2 are on said subnet and already work. when I reload the rules, I am unable to stop a connection between machine 1 and machine 2. I've already made sure that ipfw is running(loaded), and the rules appear to take, and even show up with "ipfw show". # ipfw show ... 01700 0 0 deny ip from 192.168.20.0/24 to any 01800 0 0 deny ip from any to 192.168.20.0/24 65535 9227 11389032 allow ip from any to any However, there is no effect on data travelling over the pipe at all. This setup was confirmed many times to work with FreeBSD 9.2, but it does not work on 10. any help is appreciated.
