Hello and welcome to Tom's Hardware Forums.
The address of a Netgear router is usually 192.168.0.1 and the settings you need are Port Forwarding if you want to see your camera when you're away from home. The login details are usually admin for the name and password for the password but if you're in Britain using a Sky Netgear, the password is sky.
Sadly, though, you can't change the settings you want in a Sky router without cracking the firmware.
