Brothers,
     I set my own rule of firewall using ipchains, I try to issue my own
rules with this line...
   ipchains -F
   ipchains -A input -s mynetwork/subnet -p TCP ACCEPT
   ipchains -A input -s 0/0 -p TCP DENY

I know somethings wrong w/ my rules, how can i Deny only the port like
(telnet or ftp) using ipchains?, the thing is, only the port 53, 21,22 that
i just want to filtered out, how can i do this things without affecting
others port using TCP protocol?
