Metal Gear Online - Problem

Me and someone else are trying to play MGO on the same internet connection at the same time(We both play it on two different PS3s and two different accounts), but when we both want to play MGO and go to the same server or a different server, one or both of use gets disconnected. This happens periodically. Does anyone know what is wrong?

My guess is a badly thought-out anti-botting or anti-piracy measure.
