Are you relaying DHCP requests to the Sonicwall or to an internal DHCP server?  Do you have the Sonicwall handing out DHCP to clients connecting to the WLAN zone via SonicPoints?  I would recommend configuring the Sonicwall to hand out DHCP requests.

Here is how I've configured it for a client running SonicPoints on the WLAN zone.  Setup a DHCP server on the SonicWALL and assign it to the X2 interface which is the interface assigned the WLAN zone.  Also, make sure to check the box, "Enable Conflict Detection".

Go to VPN > DHCP over VPN and click the drop down and select Central Gateway.  Click Configure.  Click the checkbox "Use Internal DHCP Server" and "For Global VPN Client".  Below, in the Relay IP Address box, type in the IP address of the X2 Interface.

currently i am only using LAN (x0) and WAN (x1) ports on the sonicwall pro 240. DHCP server is enabled on the firewall. DHCP over VPN > Central Gateway > DHCP Relay > enabled Use Internal DHCP server and For Global VPN Client. On the VPN Client I am able to connect, but it doesnt know tell me the DHCP IP address. On the sonicwall i can see its 192.168.3.6, but the VPN client user cant not ping or access the inhouse servers.

Will You Be GDPR Compliant by 5/28/2018?

GDPR? That's a regulation for the European Union. But, if you collect data from customers or employees within the EU, then you need to know about GDPR and make sure your organization is compliant by May 2018. Check out our preparation checklist to make sure you're on track today!

global vpn client tells me i'm connected by the status tab for virtual ip configuration: ip address: n/w and subnet mask n/a. general tab: other traffic allowed: enabled, default traffic tunnel to peer: disabled, use virtual IP address: disabled.

So, you are utilizing an internal Windows DHCP server?  If so, I believe you'll want to configure your clients like the screen shot I've attached.  The IP address in the screen shot will represent the Windows Server that is providing DHCP on your internal network.

Also, confirm the following:

Confirm in configuration settings at VPN > WAN GroupVPN > Client tab are set as you see in the screen shot.
Check out the firewall rules between your VPN zone and your LAN zone making sure the proper traffic is being allowed.  These rules should be configure automatically when you enable the WAN GroupVPN settings.  You might try to disable the WAN GroupVPN and reenable it if the rules don't appear correctly.

thank you digitap. those screenshots were very helpful. my IE8 is pretty screwed up. i was not able to edit the GroupVPN. Everytime clicked on the edit config, i would get a new window but a blank page. I logged into my firewall with firefox browser and I was able to see config for GroupVPN and enabled DHCP Lease for Virtual Adapter settings. VPN from home and was able to get a DHCP and access the servers. Thanks again.

Yeah...IE8 no likey Sonicwall interface.  I forgot about that.  I use Firefox exclusively, but had run into that before.  Look into IE8 Compatibility mode which might clear that up.  Glad I could help and thanks for the points!
