The IP addresses look correct, 81.106.67.7 is your public IP address, 192.168.0.1 is just for your home network, 127.0.0.1 is a special one called the loopback address - dont worry about it.

First thought, do you have XPs built-in firewall enabled on the NTL network card? If you look in the network connections dialog, it may say Connected, Firewalled next to the connection icon.
