There is not a lot of information to go on, but by the sounds of it, you believe that you have established a VPN Correctly.

If this is the case, the fact that you cannot connect to the server could be a number of things. You don't tell us how you connect to the server, are you referring to Windows connectivity, or are you talking about pinging the server.

One of the first tests anyway is to confirm that you can ping the server using an IP address (not a DNS name). If the ping does not respond, then it could be that a gateway address may not be set on the Server. This is a common occurence, especially where a flat network is involved. If it doesn't know where to go to route back a ping it will fail.

That's all I can provide at the moment without further information

If your VPN client is IPSec based, make sure it can pass NAT. Besides, maybe it succeeds in key exchange (IKE/ISAKMP = UDP or TCP port 500), but fail during encryption - because the port is not opened. Standard IPsec is IP protocol 50 (not even TCP or UDP). It Netsrceen support 'UDP encapsulation', check to see which port is filtered.
