Re: Port forwrading help?

Hi David -

To do a port forward to the same system, use -j REDIRECT rather than -j DNAT, e.g. -j REDIRECT --to-ports 5222
Note that REDIRECT ignores the destination address. It redirects the packet to the specified port(s) on the local system whether the packet was originally destined for the local system or not.
That said, I'm not an iptables guru either, nor have I used REDIRECT, but I think it's what you need.
