On Sunday evening we decided to shorten up some time playing World of Warcraft in the office. We’ve set up the accounts, installed and launched the game and oops…it occured that we are not able to play, because of a strict NAT our network has. Thank you Mr. Admin! 
But I did not forget, that I have Arovax SmartHide Personal Account (I can afford it being a Project Manager of this service;) ) so a couple of minutes setting up the needed ports within our Port Forwarding feature – and here we are playing a multiplayer game having a dedicated external IP address
I am so glad that I have SmartHide on my PC
