Controlling a remote VNC Server accessing a VPN

[Jacob Hoover]

I use Symantec Enterprise VPN, however in a slightly different 
situation.  I haven't had any problems, but my main PC also is the one 
which has the VPN client on it.  I would suggest several test to better 
understand your situation.

#0
What OS are you using, is there any firewall software installed (I think my 
VPN software originally played with XP's firewall settings)

#1
do a "route print" and compare the routing tables between before and after 
the VPN is connected. (On The Machine With the VPN client)

#2
can you still ping from the Primary to Server

#3
can you still ping from the Server to Primary

#4
Check the Nortel VPN documentation!  It probably is installing a device 
driver for encrypting and tunneling of the TCP/IP data.  Is there any 
possible client side configuration that can be done? (The problem may be a 
desired "Security" feature)

#5
If all else fails, ask your network admin at work to see if they have any 
server side configurable settings which are forced to the client
