ProSecure Unified Threat Management UTM10 or UTM25 Reference Manual

When you create a VLAN profile, assign LAN ports to the VLAN, and enable the VLAN, the LAN ports that are member of the VLAN can send and receive both tagged and untagged packets. Untagged packets that enter these LAN ports are assigned to the default PVID 1; packets that leave these LAN ports with the same default PVID 1 are untagged. All other packets are tagged according to the VLAN ID that you assigned to the VLAN when you created the VLAN profile.

This is a typical scenario for a configuration with an IP phone that has two Ethernet ports, one of which is connected to the UTM, the other one to another device. Packets coming from the IP phone to the UTM LAN port are tagged. Packets passing through the IP phone from the connected device to the UTM LAN port are untagged. When you assign the UTM LAN port to a VLAN, packets entering and leaving the port are tagged with the VLAN ID. However, untagged packets entering the UTM LAN port are forwarded to the default VLAN with PVID 1; packets that leave the LAN port with the same default PVID 1 are untagged.

Note: The configuration of the DHCP options for the default VLAN are explained in “Using the Setup Wizard to Provision the UTM in Your Network” on page 2-1.” For information about how to add and edit a VLAN profile, including its DHCP options, see “Configuring a VLAN Profile” on page 4-6.

To manage the VLAN profiles and assign VLAN profiles to the LAN ports:

1.Select Network Config > LAN Settings from the menu. The LAN submenu tabs appear, with the LAN Setup screen in view. (Figure 4-1shows two VLAN profiles as an example.)
