Redirect port 80 to 8080

Question

Hey I have created a simple http server, so when i type
> curl http://localhost:8080/
I give me the respons:
> Hello World
now i want the same to happen when I type:
> curl http://localhost:80/
I could do that by changen the port that the http server is lisining on but it will require that i run it as a super user and i don't want that.
I have tryed to use the ipfw command (I have vey limited knowleged about it):
> ipfw add 100 fwd 127.0.0.1,8800 tcp from any to any 80 in
it then says:
> 00100 fwd 127.0.0.1,8800 tcp from any to any dst-port 80 in
I look at the list:
> ipfw -d -e -t -a list
it says:
> 00100   1     64 Thu Aug  4 14:47:51 2011 fwd 127.0.0.1,8800 tcp from any to any dst-port 80 in
> 65535 188 33853 Thu Aug  4 14:45:39 2011 allow ip from any to any
But when i try to get a respons from my http server:
> curl http://localhost:80/
It says:
> curl: (7) couldn't connect to host
I try to restart my computer and check the list again:
> ipfw -d -e -t -a list
It says:
> 65535 464 111936 Thu Aug  4 14:48:39 2011 allow ip from any to any
So somehow the rule has been removed.
What can i do to redirect port 80 to 8080,

Answer 1

I should have writen
sudo ipfw add 100 fwd 127.0.0.1,8080 tcp from any to me 80
I belive the important diffrent is the change from any to me in the last part.
And rules applyed to ipfw will be rested after restarting,
