Clients connected via SonicWALL only have Internet access when DHCP is enabled

I have a SonicWALL TZ 215. Default setup out of the box using the wizard with DHCP server enabled. If I assign a static IP address to a PC/server it doesn't connect to the Internet. If I change the NIC to DHCP it connects immediately.

Is there any setting on the SonicWALL to allow only DHCP clients to connect to the WAN?

On a TZ205 it works for both static & DHCP clients.

Please confirm Gateway settings when Pc/Server connects to internet and when not....
Please also verify how many subnets you are using.

When you assign a static IP address, are you adding the correct IP addresses to the gateway and DNS server fields in the NIC configuration page?

DHCP supplies this information as well as the IP address itself and the subnet mask, so if you choose to configure your computers NICs manually, all the information has to be added manually.

Also, be sure to use static IP addresses that are in the same subnet as the DHCP scope of the SonicWall, but outside the range of that scope. If necessary, reduce the size of the scope to make IP addresses available for manual assignment.

Does the TZ215 have any access control features turned on? If so, try disabling them to see if such features are causing the problem. This is most likely if you are using the WLAN capabilities of the device.

Thank you for your responses.

Following  Syed's post I checked the settings using ipconfig /all
When I manually configured the NIC I had used the SonicWALL IP as the DNS server ( The DNCP configuration was using (the IP that the SonicWALL had been configured with).

DNS settings was the issue. I'll award points to both Syed & Perarduaadastra.
