Ok, I've been trying to use redir now, but I'm running into another
problem and I suspect that it's Apache's fault and not the redirector.

real.machine.com:9000 => internal.machine.com:80

The index page that exists on internal.machine.com:80 has some links to
specific mrtg devices.  These links are just local file pointers, you know
<a href="filename.html">.  Well for some reason that I can't figure out,
when I click on one of links on the index.html page through
real.machine.com:9000, the web server tries to contact real.machine.com
and not real.machine.com:9000 therefore screwing everything up.  What
really boggles my mind is the clients seems to recognize the url and port
in the link.  When I point to the link, that Netscape status says:

http://real.machine.com:9000/filename.html

I hope that wasn't confusing.


So, is this an apache/web server httpd thing?

I'm going to try the ipautofw stuff next.

Thanks for the help.
