Whats up guys,I think im dense today because im missing something I shouldn't be. I'm running a RH7.3 system (all updates) with wu-ftpd , iptables and I used MonMotha's Firewall 2.3.8-pre9 to set the script up. I'm allowing the following TCP ports TCP_ALLOW="20 21 22 25 80 110 443" But, when I ftp to the machine and login it times out when it tries to "ls" the directory ? What am I missing ? Florian
Remove port 20 from TCP_ALLOW and execute the following (as root): modprobe ip_conntrack_ftp modprobe ip_nat_ftpIf you're running a kernel prior to 2.4.20, make sure you don't have any other conntrack or nat helpers loaded (use lsmod to check) first, as the old NAT code can only handle one at a time (2.4.20-pre2 and later have newnat merged in whcih can handle multiple helpers).
