im having a problem with proftpd access when my firewall is running. Im using centos 4.3 with proftpd-1.2.10-10.2.el4.rf
i haven't done any modification from my proftpd i just run the server. my iptables ruleset is very simple i use stateful routing.
iptables -A INPUT -i ! $WAN -j ACCEPT iptables -A INPUT -i $WAN -m state --state NEW -p tcp --dport 21 -j ACCEPT
I suspect your problem might be related to PASV ftp jumping up to a higher power. You need to set an upper and lower port bound for PASV ftp, or enable ftp connection tracking by loading the appropriate iptables module.
