Optional network settings identify your appliance to the rest of your network. If
you plan to connect to or refer to your appliance by name, you must configure
these settings.
Some ISPs authenticate by the physical (MAC) address of your Ethernet port.
This is common with broadband cable (DHCP) services. You can clone your
computer's adapter address to connect to your ISP with the Symantec Gateway
Security 300 Series. This is called MAC cloning or masking.
If the appliance is going to be a wireless access point, the optional network
settings must be set. See Symantec Gateway Security 300 Series Wireless
Implementation Guide.
For model 320, you configure the settings for the WAN port. For model 360 or
360R, you can configure the network settings for one or both WAN ports.
Before you configure optional network settings, gather the following
information:
Host name Name of the appliance. For example, marketing.
Domain name Name by which you address the appliance over the Internet. For
example, mysite.com. If the host name is marketing, the appliance
would be marketing.mysite.com.
MAC address Physical address of the WAN of the appliance. If you are performing
MAC cloning, get the MAC address that your ISP is expecting to see
rather than the address of the appliance.
