[Tutorial] How to play on Black-seraph.com (formerly coldbird.net)

[Rikyanto]

Hello, I wanna ask something. I was playing using PPSSPP ANDROID and has set the ip (pro.coolbird.net). I was try to play MH3P HD with my friend (PPSSPP PC). I can enter the guild hall, but there wasn't anyone there although I was at the same guild with my friend. I don't know how to set the DMZ on android. What must I do? Or are there any suggestion other than coolbird that would work on android?
