SonicWALL Installation Checklist
The SonicWALL requires information about the IP address configuration of your network.
Your Internet Service Provider (ISP) should be able to provide this information. If you are
unfamiliar with the terms used in the section, review Appendix B for networking basic terms
and information.
• 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 can 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 must have 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.
• 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 located on your LAN.
