I'm using a sonic wall firewall on a clients network. After setting up the VPN they way they instructed it didn't work.
I went thru the configuration with a fine tooth comb and found no discrepancies.
So I carried my laptop(192.168.168.x) to the client connected my laptop to the LAN Modem(192.168.168.x), which is connected to the external side of the firewall(192.168.168.X).
The internal address of the firewall is (192.168.1.X)
Suffice to say, it didn't work.
After paying for support from the company I was told that what I was doing could NEVER work because the Laptop was on the same subnet as the firewall.
My question is why does that make a difference ?

I may be misinterpreting what you're saying, but is this a site-to-site VPN using two sonicwalls? If so, then this scenario won't work because your laptop is not part of the protected network (it's sitting outside of the sonicwall), and the sonicwall will ignore anything from your machine. To test a VPN from one site to another, put your laptop on the protected (182.168.1) subnet and then initiate traffic between the two sites.

If you are using some kind of remote software client, then that's a different matter entirely....
