If you haven't already done so, connect the SnapGear unit to your LAN.

Set up your LAN to access the Internet
To access the Internet, each PC on your LAN must be assigned an appropriate IP
address, and have the SnapGear unit's LAN IP address designated as its gateway and
as its DNS server.
A DHCP server allows PCs to automatically obtain these network settings when they start
up. If your network does not have a DHCP server, you may either manually set up each
PC on your network, or set up the SnapGear unit's DHCP server.
(recommended) To use the SnapGear unit's built-in DHCP server, proceed to
Automatic configuration of your LAN.
If your LAN already has a DHCP server that you will use instead of the SnapGear
unit's built-in DHCP server, proceed to Automatic configuration of your LAN using an
existing DHCP server.
