• NAT with PPPoE mode uses PPPoE to connect to the Internet. If desktop soft-
ware and a user name and password is required by your ISP, select NAT with PP-
PoE.
LAN Settings
• SonicWALL LAN IP Address
The SonicWALL LAN IP Address is the IP address assigned to the SonicWALL LAN
port. It is used for managing the SonicWALL. This IP address should be a unique
address from the LAN address range.
• LAN Subnet Mask
The LAN Subnet Mask defines which IP addresses are on the LAN. The default Class
C subnet mask of "255.255.255.0" supports up to 254 IP addresses on the LAN. If
the Class C subnet mask is used, all local area network addresses should contain
the same first three numbers as the SonicWALL LAN IP Address--for example,
"192.168.168."
WAN Settings
• WAN Gateway (Router) Address
The 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 or NAT with PPPoE 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 or NAT with PPPoE mode, 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.
