If your SnapGear appliance is configured for a Direct Connection to the Internet, you must also set the IP address for the Internet Interface. Check DHCP assigned if the IP address of the Internet Interface is set via a DHCP server, or enter the IP Address and Netmask if you have a static address for the Internet interface.
Enter the IP address of default gateway in the Internet Gateway field. The SnapGear appliance will send all packets not destined for the local network to this machine.
Enter the IP address of the DNS Server that the SnapGear appliance will use to resolve domain names in the Domain Name Server field. This is only required if the SnapGear appliance is configured with a static IP address on the Internet interface and does not automatically get its DNS server address.
The SnapGear appliance can also be configured to run as a Domain Name Server. The SnapGear appliance acts as a DNS proxy and passes incoming DNS requests to the appropriate external DNS server. If this is enabled, all the computers on the LAN should specify the IP address of the SnapGear appliance as their DNS server.
