Same way you do with a normal router.Does it have more than one ethernet port on the back?
it has one ethernet port and 2 telephone ports on the back. But i can't port forward because the ip address i used to put in the address bar doesn't work anymore. plz help.
So did you use to put 192.168.1.1 in the address bar? I think thats the default router address on a network right? =\
