Sonicwall VPN and DHCP Setup

Folks

We have a customer with a Sonicwall TZ300 which they want to setup VPN client access for remote users etc...

I have got the VPN to work when I click on the 'Use internal DHCP server' and the 'for Global VPN clients' options within the VPN/DHCP Over VPN section of the unit...

The issue is the customer has an existing 2012 R2 server within the network serving as a DHCP(since they want to use the Windows server version of DHCP etc...)

Is it possible to make these 2 work together? Or how do I setup the DHCP on the Sonicwall to pass through to the internal DHCP? I tried using the 'Send DHCP requests to the server listed below' option but this doesn't seem to work.

Need some help if someone has done this or has a similar setup to the above

Thanks
Shane

Is there a "use DHCP relay" option on the SonicWALL?

Did you add the vpn scope to the windows server?

Should use the existing scope by default.

Hi ccomley

That did the trick - the issue was I had the 'Use internal DHCP' ticked as well which probably wasn't right...now I can see it connecting and getting IP from the internal DHCP - many thanks!

Rob - the relay I tried yes but also couldn't get that working...might have been swapping too many things at once which wasn't helping

Aaron - I assumed the internal scope would be fine and obviously its working - but using a different scope would be nice for sure cause I could tell VPN connections from internal connections - how do I do that on the 2012 server though? Or asked a different way how does the vpn client know to use that alternate scope?

Sorry if I need to ask this as a separate question I'll do that
