I am trying to rack my brain to remember what the name of a program was that I was looking at a few weeks ago. It was a linux program that would take incoming web traffic and internally send it to a different location.

I also seem to remember it having a strange name. But I could be mistaken.

That's not much to go on, I know. Sorry. TIA

Maybe you're thinking of Squid? The general category of software you're talking about is "reverse proxy", and there are many. Apache can do it, even.

Not exactly what I was looking at before.

The one I was looking at before would take requests to an address and blindly grab that request from a different, internal address. One of the examples was mail server access for people inside a specific IP block. I think.

Thanks

Okay, is it web traffic or mail traffic? I'm guessing you mean generic IP traffic.

This is what firewalls do. There are also any number of applications that wil blindly forward traffic. Netcat comes to mind.
