Hi. I was wondering what I would need for rules to have traceroute work through my firewall. (I have a box behind the firewall trying to get out using traceroute). I have an allow established connections on my forwared chain, and I am allowing anything from the source IP of the box in question to leave ... It appears that the problem is on the packets comming back in .. but I am not sure what I have to do to fix it .... Thanks Peter
