Best thing to do is what I do at home. Choose your main computer that will receive all the ports, set a static IP to it, and use DMZ in the linksys router. Example, set your computer to 192.168.1.2 in the Local Area Network connection under the TCP/IP settings, and 192.168.1.1 as the gateway. Then, in the router, set DMZ to point to 192.168.1.2. What that does is forward ALL ports to your computer essentially leaving you in a configuration identical to being without a router.
