Is port forwarding what you want?  Port forwarding can take stuff
that's addressed to 111.111.111.111:80 and forward it to
222.222.222.222:5000.

Or do you want to have something that is addressed to
222.222.222.222:80 changed to 222.222.222.222;5000?  The latter I
don't know how to do, but I did run across the Advanced Routing HOWTO
the other day.  I didn't read it, but it looks very interesting and
might address this issue.
