I have set up a firewall using ipchains and the bridge patch (bridgein) under potato (2.2.19). The one snag I had was although the firewall works well only letting the world see certain ports (80 & 443), it doesn't let the servers behind the firewall get out. I set up a rule that allows all traffic that originated behind the firewall out, but because we only have a couple of ports open, and we have no clue what port the reply packets are going to come on, the reply packets get denied.
I was wondering if there is any way to mark out going packets so we can let them through on their way back? Thanks, Matt
