port forwarding

Hi,

I have to install an application that has a built in tftp server. Tftp comes in on port 69. As i am not installing this application as a root user i am running into trouble because only the root user can listen to ports < 1024. So changing the port i listen to to one greater than 1023 isn't an option neither is installing the software as root user. Is there anything i can do in unix similar to iptables in linux that could forward anything that comes in on port 69 to a port greater than 1023 lets say 4000 then have my application listen to 4000 to recieve tftp traffic.

Cheers,
Joe.

As far as I know, you will always need to do something as root to do that. Even if you use iptables.
