SonicWALL Installation Checklist
The SonicWALL requires information about the IP address scheme of your network.
Your Internet Service Provider (ISP) should be able to provide this information.
• SonicWALL LAN IP Address
The SonicWALL LAN IP address is the address assigned to the SonicWALL LAN port
and is used to manage the SonicWALL. It should be a unique IP address from your
Local Area Network (LAN) address range.
• LAN Subnet Mask
The LAN Subnet Mask defines the range of IP addresses that are located on your
LAN.
• WAN Gateway (Router) IP Address
The WAN Gateway (Router) IP Address is the address of the router that connects
your LAN to the Internet. If you have cable or DSL Internet access, the router is
probably located at your ISP.
• DNS Addresses
The DNS Addresses are the addresses of Domain Name Servers, either on your LAN
or the Internet. These addresses are required for downloading the Content Filter
List and for the DNS Name Lookup tool. The DNS addresses should be supplied by
your ISP.
• Mail Server (Optional)
The Mail Server address is the name or the IP address of the mail server used to
E-mail log messages; it may be a server on your LAN or the Internet. For best
results, use the same server used on your LAN for E-mail.
If you are using Network Address Translation (NAT), then you also need the
following information:
• SonicWALL WAN IP (NAT Public) Address
The SonicWALL WAN IP (NAT Public) Address is the valid IP address that your
entire network uses to access the Internet. This address should be supplied by your
ISP.
• WAN/DMZ Subnet Mask
The WAN Subnet Mask defines which IP addresses are connected to the WAN port
of the SonicWALL but not accessed through the WAN router. This subnet mask
should be supplied by your ISP.
