Nat With Dhcp Client Configuration - SonicWALL TELE3 SP Administrator's Manual

NAT with DHCP Client Configuration

The SonicWALL can receive an IP address from a DHCP server on the Internet. If your ISP did
not provide you with a valid IP address, and instructed you to set your network settings to
obtain an IP address automatically, enable NAT with DHCP Client. NAT with DHCP Client
mode is typically used with Cable and DSL connections.
To obtain IP settings dynamically, complete the following instructions.
1. Select NAT with DHCP Client from the Network Addressing Mode menu.
2. Enter a unique IP address from your LAN address range in the SonicWALL LAN IP
Address field. The SonicWALL LAN IP Address is the address assigned to the SonicWALL
LAN and is used for management of the SonicWALL.
3. Enter your network subnet mask in the LAN Subnet Mask field. The LAN Subnet Mask
tells your SonicWALL which IP addresses are on your LAN. The default value,
"255.255.255.0", supports up to 254 IP addresses.
4. Click Update. Once the SonicWALL has been updated, a message confirming the update
is displayed at the bottom of the browser window. Restart the SonicWALL for these
changes to take effect.
Note: When NAT is enabled, designate the SonicWALL LAN IP Address as the gateway address
for computers on the LAN.
