About connecting to the outside network
The Symantec Gateway Security 400 Series WAN/ISP functionality lets you configure connections to the
outside world. This can be the Internet, a corporate network, or any other external private or public
network. WAN/ISP functionality can also be configured to connect to an internal LAN when the appliance
is protecting an internal subnet. Configure the WAN connections as soon as you install the appliance.
You can configure or change the appliance's connectivity on the WAN ports using the Setup Wizard or the
WAN/ISP windows. The Setup Wizard is run automatically the first time you access the appliance after you
complete the hardware installation.
Before you start configuring a WAN connection, determine what kind of connection you have to the outside
network, and based on the connection type, gather information to use during the configuration procedure.
See the Symantec Gateway Security 400 Series Installation Guide for worksheets to help you plan the
configuration process.
Symantec Gateway Security 400 Series models 420 and 440 have one WAN port to configure. Models 460
and 460R appliances have two WAN ports that you can configure separately and differently depending on
your needs. Some settings apply to both WAN ports, while other settings apply specifically to WAN1 or
WAN2.
Warning: After you reconfigure WAN connections and restart the appliance, network traffic is temporarily
interrupted. Once the appliance is restarted, VPN connections are automatically reestablished.
