I am trying to set up a FFreebSD 2.2.6 machine to server as a communication gateway for my local network. I have a canle modem which is conected to the FreebSD box using a second ethernet card. I am using NAT to allow the other machines on my network to access the outside world. All this works fine, using the ipfw rules sugested in the NAt man page. However since this is a full time connections, with a fixed IP address, I am feeeling a bit paranoid. I would like to set up a reasonable set of firewall rules for ipfw. I started witht eh default /etc/rc.firewall, but it was not very usefeul. I think I have worked through most of what I need, but I am having problems with NAT being denied permission to write back packets it has translated. Could someone sugest a rule to allow NAT to work with a firewalled system? I would alos be interested in seeing other peoples firewall rules for similat systesm. No sense in being hacked, because I am unwilling to lear from others experience, is there?
