Thomson Gateway Nat problems

Guys if can help. I have a thomson gateway tg782 router. I need help because every time I play modern warfare 2 the Nat type is :strict. I know how to change this in the router configuration page is just I don't know the router log-in. Admin: Password: <-- this is what I don't know so if anybody can tell me what it is I will be very thankful.
