Port Redirection

[Warren Raquel]

Ok, I'm just playing around with this a little. I need to figure out how to get (for example) port 80 to redirect to port 8000 on the SAME computer using iptables. I tried a google search but my head is exploding and all I can find are examples for forwarding to machines inside your lan. The direction is from the world to the my computer. It's not a router, it's stand-alone. Any tips?
