I've been enjoying multiboxing a lot with help from keyclone on one machine. But naturally 5 instances of wow slow the machine down quite a lot for high stress areas. So I tried to switch to two machines today.

I bought a second license; copied over the necessary game directories; and entered the Main computer's IP info into the secondary computer. I made sure to run as admin and also open ports. When I enter the IP info, it shows the connection briefly with a light blue highlight and pings a few times, then makes the noise it makes (a loud bing noise) when closing and closes. I never see evidence on the first computer that it has recognized the second computer. I have tried to search lots of keywords on the forums but can't seem to find other people having this issue. What am I doing wrong?
