CentOS - Oct 2008 - iptables local forwarding

Hi

I am trying to forward port 80 to 8080 locally using iptables with the 
following

/sbin/iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT 
--to-port 8080

However this does not get put into the iptables configuration even after 
running iptables-save

Have i missed something along the way?

thanks

iptables-save will only output the rules in a way that
iptables-restore will be able to rebuild the rules from.

If what you want is for these rules to be up when you boot the
machine, what you want is probably "service iptables save", which will
use iptables-save to record these rules to /etc/sysconfig/iptables,
and a script automatically calls iptables-restore to read that file
upon boot.

Try adding it manually to the iptables config.

# vim /etc/sysconfig/iptables

And then restart iptables.
