Fedora Users — Re: iptables on FC11

Thanks for the suggestion, that is exactly what happened.
I was misled by an internet suggestion that nmap was a good tool to check iptables configuration, but that is not true.
iptables -L gives the correct information

I upgraded from FC9 to FC11 (new install) but iptables is behaving strange. My /etc/sysconfig/iptables file shows a number of ports as accept, but nmap tells a different story. e.g. imap port 143 is closed in nmap (and in truce), open in iptables file.
I did use the iptables GUI to configure.

Any idea what I am overlooking.

greetings, Paul van der Meij

What does 'netstat -atn' tell you? If iptables allows connections to tcp 143 but there is no application listening on the port, that could explain what you describe.
