I'm sorry. I wasnt clear in my first post. A situation arises when my router gets restarted, the internal ip addresses of the computers in my home (192.168.1.100 and the like) are shifted around. Normally I have the router forward some ports to one of my computers for a few services that I like to have, like an ftp server. What I want to do is create a perl script that runs in cron that will make sure my router is forwarding the ports I want it to. But the thing is, the only interface I know of for doing such things is the web interface to my router. It needs the mouse to select checkboxes and fill in textboxes. It would be great if I can script this action to run on a regular basis especially since Im not always home when the ips get switched around.
