Dear friends

i have configured iptables for Redhat Linux 9.0.
ftp server must pemit trusted ip to connect to ftp server.
i have done configuration below:

iptables -A INPUT -p tcp -s 0/0 -d 0/0 --dport 21 -j DROP
iptables -A INPUT -p tcp -s <your trusted pucblic ip> -d 0/0 --dport 21 -j ACCEPT

but it closes connection between clients and ftp server!!!!!!!

what is the problem????????

You may want to try reversing the order of those rules. Iptables handles the packet according to the first rule that matches, so the packet may get trapped by your -s 0/0 rule.

You are going to have to be more specific. Did you change the rule order? If you did, what is happening? Have you checked the logs?
