The VLAN Settings Page contains the following fields:

2. Select the VLAN name from the VLAN ID list and click Add. This VLAN name then appears in the Enabled
VLANs list.
3. Click Save Config on the menu to save the changes permanently.
Defining Trusted Interfaces
The Trusted Interfaces Page allows network manager to define Trusted interfaces. Trusted interfaces are
connected to DHCP servers, switches, or hosts which do not require DHCP packet filtering. Trusted interfaces
receive packets only from within the network or the network firewall, and are allowed to respond to DHCP
requests. Packets sent from an interface outside the network, or from beyond the network firewall, are blocked by
untrusted interfaces.
Conversely, untrusted interfaces can be configured to receive traffic from outside the network or the firewall.
