sorry its in the wrong forum,

i run win2k server, my wife win ME, basically i bought the router for firewall purposes, no network really, we have two machines (active) we both have our own ip assigned by our ISP, i configured the router to let us out on the net and get email, but what i want to do is set it up like zone alarm, kind block incoming traffic if not wanted.

we have a cable modem (rj45 jack) hooked to wan port of router, then just cat5 cable from router to each machine( patch cable) i guess i want to set up router to block the same as software firewalls do. just dont know where to start.
