Ensure that you haven't used the "require security client for this connection" for the GroupVPN.

In general, the client setting to allow it to split tunnels is the setting that allows it to access the internet, so that should be all you need.

I would also recommend that you upgrade to the latest version of the GVC (v4 is now RTM) and if possible, try to re-create the GroupVPN SA just to ensure that you're setting it exactly as you want...

I had the same problem trying to access internet traffic through a VPN connection. I followed this documentation from sonicwall and added the WAN rule on page 14 and it nailed the problem. http://www4.nohold.net/noHoldCust301/Prod_1/KnowledgePortal/KPScripts/amsviewer.asp?docid=6999ff1d6100416691f1a53e104cd0ab_GVC_sos25e_Route_All_Traffic_through_a_SonicWALL.pdf&amsstatsid=331303

In regards to setting up split tunnels, could you post your settings in the Client section of the WAN group VPN.

To access the Internet through your ISP while connected through Sonicwall Global VPN Client (split tunnel), follow these steps:
The VPN > Settings page provides the Sonicwall features for configuring your VPN policies. You configure site-to-site VPN policies and GroupVPN policies from this page. Click the Edit icon for the GroupVPN entry. The VPN Policy window is displayed.
1.      Click the Advanced tab. Set Default Gateway to 0.0.0.0.
2.      Click the Client tab. Set Allow Connections to - Split Tunnels.
3.      Uncheck Set Default Route as this Gateway.
4.      Click OK.
5.      Right-click the VPN connection policy in the Sonicwall Global VPN Client window, and select Disable.
6.      Close the Sonicwall Global VPN Client application (from system tray as well).
7.      Launch the Sonicwall Global VPN Client, right-click the VPN connection policy icon and select Enable from the menu.
 If the above settings do not provide a resolution:
On the client PC open a Command Prompt and type the command:  route print.  The route print should show only one 0.0.0.0 0.0.0.0 route with the default gateway configured on the client PC.
If configured properly the Sonicwall will provide single routes for the destination networks that can be reached over the GVC connection.
If there are two 0.0.0.0 0.0.0.0 routes and if the Connection Details on the Connection Status shows 0.0.0.0 0.0.0.0 this can be caused due to:
     1.    Set Default Route as this Gateway is checked on the GroupVPN configuration
     2.    On the VPN Access TAB on either user or group properties on of the following objects is configured:
            - Firewalled Subnets
            - WAN Subnets
In case of the latter, remove these and exchange them with more specific Address Objects and/or Groups.
To access the Internet through the Sonicwall while connected through Sonicwall Global VPN Client (route all tunnel), follow these steps:
Sonic Standard firmware:
The VPN > Settings page provides the Sonicwall features for configuring your VPN policies. You configure site-to-site VPN policies and GroupVPN policies from this page. Click the Edit icon for the GroupVPN entry. The VPN Policy window is displayed.
1.      Click the Advanced tab. Set Default Gateway to the IP address of a LAN based router / second Firewall.
2.      Click the Client tab. Set Allow Connections to - This Gateway Only or All Secured Gateways.
3.      Check Set Default Route as this Gateway.
4.      Click OK.
5.      Right-click the VPN connection policy in the Sonicwall Global VPN Client window, and select Disable.
6.      Close the Sonicwall Global VPN Client application (from system tray as well).
7.      Launch the Sonicwall Global VPN Client, right-click the VPN connection policy icon and select Enable from the menu.
Sonic Enhanced firmware:
The VPN > Settings page provides the Sonicwall features for configuring your VPN policies. You configure site-to-site VPN policies and GroupVPN policies from this page. Click the Edit icon for the GroupVPN entry. The VPN Policy window is displayed.
1.      Click the Advanced tab. Set Default Gateway 0.0.0.0.
2.      Click the Client tab. Set Allow Connections to - This Gateway Only or All Secured Gateways
3.      Check Set Default Route as this Gateway.
4.      Click OK.
5.      If DHCP over VPN is used:
1.      Add a NAT policy:
2.      Original Source: Vpn DHCP Clients  
3.      Translated Source: WAN Primary IP
4.      Original Destination: Any
5.      Translated Destination: Original
6.      Original Service: Any
7.      Translated Service: Original
8.      Inbound Interface: Any
9.      For the OutBound Interface select the Primary WAN port
10.      Set Enable NAT Policy
11.      Do NOT set Create a reflexive policy
12.      Click OK.
6.      if DHCP over VPN is not used:
1.      Go to the NAT Policy Table
2.      Locate the default Policy with Original Source: Any and Translated Source: WAN Primary IP the Sonicwall has created for Inbound Interface is LAN Port and Outbound Interface is WAN port
3.      Edit this rule
4.      Change Inbound Interface to Any
5.      Be careful with this in case a NON Natted DMZ port is used
7.      Right-click the VPN connection policy in the Sonicwall Global VPN Client window, and select Disable.
8.      Close the Sonicwall Global VPN Client application (from system tray as well).
9.      Launch the Sonicwall Global VPN Client, right-click the VPN connection policy icon and select Enable from the menu.

I would upgrade to GVC version 4.0

Hi,
I used this solution and it worked for me.  Not sure if there are any security implications though?

Tnx,
