FTP problem thru IPCHAINS

[Paul Tan]

HI everyone,                     I'm pretty new to IPCHAINS, ok i've setup a very basic firewall which does MASQ for my workstations ,                   #ipchains -A forward -s 192.168.128.0/24 -d 0/0 -j MASQ                   everything going thru this connection is pretty much ok, except for FTP, i can connect to ftp.redhat.com or ftp.webmin.com , but as soon as i do a "ls" , they say i have issued an illegal command......                   thks in advance...your experiences would be greatly appreciated.   rgds, Paul
