got do this or not?

told a friend to do this, it improved for him (for myself too)

all online games, and torrent will use port forwarding. Setting it into your router will enhance the performance/bandwidth usage of the applications.

I'm using P1 so I studied the concept and applied the settings to my modem. After which torrent downloading is much more faster.

Other games like League of Legends also got their own Port settings

use this page http://portforward.com/ (as provided by blizzard), search your modem model, it will lists down step by step on how and what to add.
