請問如何使用代理伺服器去玩海外的線上遊戲?

First, you have to make sure if this overseas online game server accepts connections from proxy servers.

Second, identify a workable proxy server.

Third, set your Explorer to connect through the proxy server.

Fourth, connect to the overseas online game server to play the game

But...unless you have something evil in mind, I cannot see any reason of playing online game through proxy...simply because the issue of speed!
