8. Click Update. Once the SonicWALL has been updated, a message confirming the

If you enable Network Address Translation, designate the SonicWALL LAN IP
Address as the gateway address for computers on your LAN. Consider the following
example:
• The SonicWALL WAN Gateway (Router) Address is "100.1.1.1".
• The SonicWALL WAN IP (NAT Public) Address is "100.1.1.25".
• The private SonicWALL LAN IP Address is "192.168.168.1".
• Computers on the LAN have private IP addresses ranging from "192.168.168.2" to
"192.168.168.255".
In this example, "192.168.168.1", the SonicWALL LAN IP Address, should be the
gateway or router address for all computers on the LAN.
