[Macpartners] mapping ports on http requests

[Allan Doyle]

One solution is to run an httpd on port 80 and then use mod_rewrite  
rules to proxy from port 80 to port 8000. Depending on what's  
happening on the port 8000 server, this can range from easy to a bit  
tricky.

Another thing you might try is to run a shell script (as root) using  
ssh to tunnel port 80 to port 8000. Usually tunneling is used to go  
between machines but there's no reason it would not work locally.
