First I want to thank you for your work, yesterday tested the version with iptables and it worked, zero pb guid for cracked players, and real pb guid for normal players.

This server I took the screenshot does not use any of these tools, it is a windows server 2008 r2, and the executable "IS0-m1ck", disabled firewall. For this reason I thought it strange these guids, and at the same time thought it would be possible to make another server, resulting in the same pb guids.
