Hey dude, how are u ?

Well, i'm developing a private server of Sudden Attack, an old game distributed by Nexon, and in Brazil is not available anymore, so we decided to open our private server, but the game room run in P2P.

My question is, i can use this program as a NAT server ? To allow conection between the players ?
