Hi Gurus,
I am using Red Hat Linux 7.0 which acts as an proxy server(Transparent Squid), and firewall server(Ipchains). I use dial-up connection. My problem is whenever i connect to an ftp site my get this error:-
~ Login completed.
PORT 10,1,11,11,8,230
< 500 Illegal PORT Command ~ Could not retrieve directory listing for "/"
Below is my firewall rules:-
:input ACCEPT :forward ACCEPT :output ACCEPT :pbi - -A input -s 10.1.0.0/255.255.0.0 -d 0.0.0.0/0.0.0.0 80:80 -p 6 -j REDIRECT 3128

Please let me know what is wrong in my rule, so that ftp-sites can connect smoothly.
Warm Regards,
