Guide to play MHFU / MHP3rd on a public server like socom.cc without using VPN

[DeLeo_77]

I had connection issues when playing MHFU and MHP3rd multiplayer on socom.cc, I used to break off when the quest start and I didn't want to use a VPN.
After doing some tests and research, I solved the problem and I can play without issues.
A LOT of players have connection issues when playing so I decided to make a guide.
Please share it with players that have issues when playing on socom.cc or any other public server.

That is such a nice guide with explanation of various scenario!
And these scenarios are not only valid for MH games but for most adhoc games in general (since most adhoc games worked like P2P instead of Client-Server way)

Games that use PTP (TCP) protocol to communicate during game play only need the listening side to have open port (due to connection-oriented nature, once a connection has been established both side can send/recv data without issue), while games that use PDP (UDP) protocol during game play will need both sides to have open port (due to connectionless nature) to be able to receive data.
