Port forward help please

hanxuerui · 05-04-2003, 11:23 PM

I have searched the forum, there are some topic talking about iptables that seems could do what I needed.

What I am doing is: I want to run my web server on 8080 by using another userid other then root. But port 80 will not available for a regular user id. Then I think I need a port forward, forward a request from 80 to port 8080.

I tried a couple times, but it it just not working for me.

Can somebody please write the command down here?

The error information is:
2003-05-05 07:51:10,107 : Http11Protocol.init : Error initializing endpoint
java.net.BindException: Permission denied:80

With root id as the service id it is okay.

here is my answer: to the same machine from 80 to 8080:

iptables -t nat -I PREROUTING 1 -p tcp --dport 80 -j REDIRECT --to-port 8080
