I just put together a new firewall at the house. It is a fresh install of Potato with a 2.2.19pre17 re-rolled with IP Firewall support and the IP-Masq-ftp, and IP-masw-pptp modules installed. Then I installed IPCHAINS, IPMASQ, and IPMASQADM. The box makes a pppoe connection to my DSL provider at bootup and then it starts the masqrading. This generally works fine. But I must have some prt block, becasue I cannot get out from behind the firewall to certain ports (i.e. 10000). With the ipmasq-modules I have no problems with pptp or ftp from behind the wall. And most traffic is fine (web, tribes2, etc.). I was going to modify some of the IPchains rules, but I noticed this. When I flushed the rules IPCHAINS -F. They dissapeared, but soon returned. How did they get back ? Also, I have not been able to get ipmasqadm working. I have used this befoire without problems, but for some reason my port forwards dont work. Any suggestions on determinig exactly what I have forgotten. Why wont impasqadm work ? How can I fully manage this firewall ? It seems krules are being applied from somewhere I have not checked.
Thanks! Ben
