How to host games (e.g. Call of Duty) with the Siemens 4200 ADSL Modem?

Question

I read that the modem was not really made for hosting games, but there is a work around to it. I don't know how true this is but i would like someone who is familiar with the modem to tell me how to set it up for hosting games. I have already tried port fowarding, NAT Only and configuring my firewall (Windows). Please, help me!!!!
