Server not showing

Hello i have installed BF3 and Vu and basically wanted to set up a server where i could play against the bots. And I tried to set it up like it says in the wiki but its not showing up on VU’s server list. Not sure what to do. I had tried to install vu a year or two ago and got a server running but Not sure now if i did something wrong with the set up or whether its just that its all been updated since then. I would appreciate any feed back. Thanks
