How to Set up Port Forwarding on a Router

1. 1
   The first step is to go to your router's "web page"

   • 

     Enter 192.168.1.1 Into your address bar
     If your router asks for a username and password, the default setting is no username and the password is "admin"
   • on Linksys routers its "admin" for both user and password.
   • on Netgear Routers its "admin" for username and "password" for "password"
