Norton blocks VPN using Nortel Contivity

Message from Nortel Contivity: "The secure Contivity VPN connection has been lost. Click Connect to re-establish the connection." I have followed the advice of one of the posts and entered 3 different trust controls in the network security map for the server to which I am connecting (galileo)----but still no success.

 

I just purchased and installed Norton last Sat night after using McAfee for 3 years. If this problem doesn't get solved, I'm returning the product and going back to McAfee. I am a home travel agent and this is keeping me from doing my job and earning a living.

 

I use MS XP SP3 Media Center Edition.
