I just installed CentOS4 on my main server. It runs proftpd and is not NATted.. When I did the install I said to allow FTP and HTTP. I can ftp from windows dos ftp client. In IE I get "Unable to build data connection: No route to host" ncftp I get.. Data connection timed out. Falling back to PORT instead of PASV mode. List failed. Wget and FireFox just time out. Anything I need to add to the firewall rules? This is all it has related to FTP. -A RH-Firewall-1-INPUT -p tcp -m state -m tcp --dport 21 --state NEW -j ACCEPT
