Hi,
I have an existing iptables as follows:-
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter

How do add a redirect port 26 to 25. I had googled the net and notice that
the
syntax is different
iptables -A INPUT -p tcp --dport 26 -j ACCEPT
iptables -A PREROUTING -t nat -p tcp --dport 26 -j REDIRECT --to-port 25
regards
