Hi, I am trying to set up a web serve on my computer. However, I am behind a Linksys Router (firewall included of course). When I set up an ftp server, I could just forward all traffic on port 21 to my computer, but since other computers are connected to the router as well, I can't just forward all port 80 traffic to this computer. What is the best way to deal with this? Thanks for your help. -nuj

Found toooooo many links available for you. Google to setup web server behind router

What you're looking for is a DMZ; that's a computer on the LAN that the LAN excludes from "local" traffic. Some routers come with a DMZ setting, others don't. To set up your web server you must assign it a FIXED IP Address and tell the router to treat this address as a DMZ with such-and-such ports open (usually all of them). If your router doesn't support DMZ then you have to port-forward the necessary ports to this PC and install software firewalls on all your other clients and tell them to treat the web server's IP Address as part of the "Internet", rather than as "local" or "trusted". The webserver PC must have a good AV installed and set to update its definitions at least once a day. Here's what happens: Through either DMZ mapping or port forwarding PCs out on the Internet can now "see" the webserver and access it directly. They will still be unable to "see" the other clients on your network or interact with these. If someone manages to plant a worm on your web server it will try to infect the other clients but the router's DMZ settings or the other clients' firewalls will prevent this. They will still be able to "see" and send packets to the webserver, just like any other webserver out on the Internet. You should only open the ports you need to run your services. Some DMS-capable routers open all ports on the DMZ machine by default, with some you can limit this to just the FTP, HTML, and maybe a game-server port or 3.

you can forward all incoming port 80 to your computer for web server because your web browser will not use port 80 to open web page.
