Miscellaneous: Multiple Computers In House

[Castaway]

Hey there!

I was reading up on the rules of this server ( Project 1999 ), and I see that you can not multi-box. However, by this rule it disables my brother, my cousin and I playing on the same server because we all live in the same house, with the same IP. Is there a way that we can enable it to where can all play on the same server, project 1999 and not get banned?

Thanks.
