to your Internet router on the same subnet. All users on the subnet you are configuring
must use this IP address as their default router/gateway address.
• Subnet Mask - This value defines the size, and based upon the Network Gateway
entry, the scope of the subnet. If you are configuring a subnet mask that currently
exists on the LAN, enter the existing subnet mask address into the Subnet Mask field.
If you are configuring a new subnet mask, use a subnet mask that does not overlap
any previously defined subnet masks.
Note: The SonicWALL cannot be managed from any of the additional Network Gateway
addresses. You must use the IP address set as the LAN IP address of the SonicWALL. Also,
you cannot mix Standard and NAT subnets behind the SonicWALL.
WAN Settings
• WAN Gateway (Router) Address
The WAN Gateway (Router) Address is the IP address of the WAN router or default
gateway that connects your network to the Internet. If you use Cable or DSL, your
WAN router is probably located at your ISP.
If you select NAT with DHCP Client or NAT with PPPoE mode, the WAN Gateway
(Router) Address is assigned automatically.
SonicWALL WAN IP Address
The SonicWALL WAN IP Address is a valid IP address assigned to the WAN port of the
SonicWALL. This address should be assigned by your ISP.
If you select NAT Enabled mode, this is the only address seen by users on the
Internet and all activity appears to originate from this address.
If you select NAT with DHCP Client, NAT with PPPoE, or NAT with L2TP Client
mode, the SonicWALL WAN IP address is assigned automatically.
If you select Standard mode, the SonicWALL WAN IP Address is the same as the
SonicWALL LAN IP Address.
• WAN/DMZ Subnet Mask
The WAN/DMZ Subnet Mask determines which IP addresses are located on the
WAN. This subnet mask should be assigned by your ISP.
If you select NAT with DHCP Client, NAT with PPPoE, or NAT with L2TP
Clientmode, the WAN/DMZ Subnet Mask is assigned automatically.
If you select Standard mode, the WAN/DMZ Subnet Mask is the same as the LAN
Subnet Mask.
