i have a bit of an odd setup that I have to work with, a linksys router sharing a broadband connection, which forwards port 80 to a linux box, which is hosting a web page. But also there are several webcams throughout the building, all with their own ip addresses and built in web pages. What I need to be able to do is without opening more ports on the router, somehow pass each camera through the linux box and out through the router. I was thinking of mabe a page with each camera name on it, and forword you there when clicked.

But if thats not possible, I can open multiple ports to the linux box if needed, the goal is to not allow direct access to the internal webcams through the router.

Hope that makes sense :S

depending on the linux webserver used, you could url rewrite or proxy the webcam pages or mirror them
Apache has all the modules necessary to do that..
