me and my brother want to play sharing same router

[Wolfgame]

Hello, me and my brother are excited about playing this server, but we share the same router and its my understanding this game is strict if two IP's are identified, ive checked the FAQ and rules in the library but I cant find specifically how we can seperate ourselves from the multiboxxers and be approved single use account holders? can someone of knowledge please assist, I dont want to log on in both comps tonight if its an issue that could result in ban, please help.
