I had problems with using VPCs (on linux platform) and the basic 48 page tutorial was not so clear ,
but I solved them today after watching this:http://www.firstdigest.com/2009/03/how- ... virtual-pc
Key points: the order of actions is important, something that I overlooked while reading the tutorial, but when you watch a video you realize the order things should be done.
And the last thing that gave me a hard time and I had to see the video a second time to notice was that the values of local and remote ports are reversed in gns nio ports configuration compared to what you have in vpc running. So pay attention!
