Configuring the SonicWALL in NAT Enabled Mode
This section describes configuring the SonicWALL appliance in the NAT mode. Essentially, NAT
translates the IP addresses in one network into those for a different network. As a form of packet
filtering for firewalls, it protects a network from outside intrusion from hackers by replacing the
internal (LAN) IP address on packets passing through a SonicWALL with a “fake” one from a fixed
pool of addresses. The actual IP addresses of computers on the LAN are hidden from outside view.If
you are assigned a single IP address by your ISP, follow the instructions below.
Tip Be sure to have your network information including your WAN IP address, subnet mask, and DNS
settings ready. This information is obtained from your ISP.
The SonicWALL Installation Wizard simplifies the initial installation and configuration of the
SonicWALL. The Wizard provides a series of menu-driven instructions for setting the administrator
password and configuring the settings necessary to access the Internet.
