Your NetDefend firewall allows you partition your network into several virtual
LAN networks (VLANs). A VLAN is a logical network behind the NetDefend
firewall. Computers in the same VLAN behave as if they were on the same
physical network: traffic flows freely between them, without passing through a
firewall. In contrast, traffic between a VLAN and other networks passes through
the firewall and is subject to the security policy. By default, traffic from a VLAN to
any other internal network (including other VLANs) is blocked. In this way,
defining VLANs can increase security and reduce network congestion.
