User manual

To have your SnapGear unit obtain its LAN network settings from an active DHCP server

on your local network, check DHCP assigned. Note that anything in the IP Address,

Subnet Mask and Gateway fields are ignored.

You may also enter one or more DNS servers. To enter multiple servers, enter each IP

address separated by commas.

Firewall class

The Firewall class setting controls the basic allow/deny policy for this interface. Allowed

network traffic is accepted, denied network traffic is dropped. Dropped means network

traffic is denied silently, no response such as “connection refused” is sent back to the

originator of the traffic.

The following table details the policy associated with each firewall class. Note that VPN

and Dial-In connections are assigned a firewall class of LAN by default.
