Unable to play with my brother because we live in the same house??

[Seetherrr]

I have been WFH because of the Corona virus and I saw some people playing P99 on Twitch and it got me nostalgic so I talked to some of my friends and we decided we wanted to play together. My brother and I have gone through the hassle of getting windows partitions set up on our Macs and going through the entire installation process and now that we both got through it we found that when trying to login to the server it states "this IP has a temporary block on it". I understand that dual boxing is not allowed and that could be why the IP is blocked but we both registered our accounts with different cell numbers / email addresses. Is there any way that we can play together without having to jump through more hoops (I know I could use a VPN but that's another pain to set up).
