I've been sifting through alot of information.. not sure what fits my needs. First of all. Am I correct in presuming that I can tell my linksys (V1.42.3) that if an address like 111.222.333 is typed in from a computer going through the router, to direct those calls to a specific machine?(mac address)? If so, I just wanted to learn these basics. I thought I'd like to take a basic test web page file, in a basic shared directory. and see if I can get calls (only from the LAN for now) to be directed to that page. So typing an address like 111.222.333 will go to the router, and be directed to the machine (mac address) I selected. I presume I then have to tell the machine what to do when calls come in, and what dir/file to access. Right now I'm just working on winxp to winxp contact.. but when I have a better understanding of those basics, I'll be bringing my linux on line, and moving to that next stage. If someone knows of a step-by-step page on how to do this, please list it.. if you have the patients to explain it, I'll do my best to follow it.. and when I have it down, make a help page with screen captures on this, to donate to this site on this subject. thanks. PS: I was triing out this exercise because aside from the server/router learning experiance, useing browser/web like access to shared files would be cooler.
