yea..
if you got that linksys 4 port, first of all, upgrade to the latest 1.42.6? firmware
then type (in IE) "http://your.routers.ip"
and it will load up a page, then go to advanced settings, and port forwarding, and set port
"113" to "113" to 168.192.0."xxx"
xxx = your computers last 3 digits of the IP when you run ipconfig
it should be either 100 or 101, depending on how the dhcp server set you
