[SOLVED] can't host?

Hello, I have finally open all my ports for mw2 and I hosted a privet match with one of my mates perfect, but I want to be able to host public mw2 hacked server I enter this code into the console just before I enter the game lobby "party_hostmigration 0; party_connecttimeout 1; badhost_endgameifisuck 0"

When I click team death match or any one game type it just stays there trying to search for available games, my nat type is open

Thank I really need help
