DHCP on Global VPN

I have a Sonicwall TZ that I am connecting to OK.
I have it steup for the Sonicwall to be a DHCP server and when I connect via VPN the Sonicwall DHCP gives me the address.

I also have a Windows 2008 server that has DHCP turned on (Split scope).
I would like to use the Windows server as the only dhcp server, but the problem occurs when the Server is off, I do not get an IP address. I would still like to "get on" the remote network so I can use iLO on the server to turn it back on, etc..

Is there a way to set the sonicwall DHCP to only give addresses to the sonicwall VPN clietns?

Please see my screenshot below on how to configure DHCP for GVC connections.  It is probably easier if you also exclude a portion of your LAN's DHCP scope to accomodate GVC clients so that you don't have conflicts.

Sonicwall DHCP over VPN config

Yes I have a coupl clients setup that way. The problem is that the Sonicwall ends up giving out IP addresses to internal machines.. and then the they do not show up properly in Windows DNS..

I would like to use the SonicWall DHCP only for GVC endpoints.

Any suggestions?

Setup shop reservations based on MAC address only on your sonicwall dhcp  daemon. This way only machines with known MAC addresses can acquire an IP from the sonicwall dhcp server.

Does that make sense?

iT IS THE OPPOSITE.. I do not want the Sonicwall to give any addresses to internet "shop" pc's

I only want the Sonciwall to provide GVC addresses

That was supposed to be dhcp:)

And you CAN do this. I think if you give your sonicwall a dhcp reservation for your remote machine, when your server fails and you need to get to it remotely, that is the only IP your sonicwall will provision.

i gave the author the solution for connectivity when emergency remote access is required.

The solution allows the sonicwall to ONLY. assign a static IP to know MAC addresses.

I never implemented this. I am guessing it will work but is not the solution I was looking for, I need to keep the primary DHCP on the Server, but want to get and address automatically. In lieu of doing it with the somicwalll DHCO and assigning each available IP to a MAC, it is almost as easy to manually assing a static IP outside of the internal Server's DHCP range..
