Is there a way to assign a static IP address to one of my computers from my router? Right now all of my comptuers are getting their IP addresses dynamically from the router (192.168.100, 192.168.101, etc...). But this is getting to be a pain for my linux box that I am using as a web server, because everytime I restart my router or my router decides to reassign IP addresses, I have to hop on my linux box to findout what it's IP address is again so I can set up the forwarding on my router to go to it's new IP address.

So I'm wondering if there's a way to assign a static IP address to my linux box, either with the router or with the linux box, so that I don't have to keep tabs on my box and router to see if they are still talking correctly?
