I recently downloaded a free beta version of gamerail to achieve better routing to game servers. But, I have heard that the same thing can be achieved by setting up a vpn. I was wondering if anybody would know how this process would be of setting up a vpn to achieve better routing to a server. Or is this all just a misunderstanding.

Well virtual private networks would not help if you were planning to connect to a public server (i.e. one that you don't know the mod of); however, if you plan to play with friends online, it is exelent. Virtual private networks create a network that your friends can join and makes it a thousand times easier to play games together. Hamachi is a great one. I hope this helps
