LAN Configuration

ProSecure Unified Threat Management (UTM) Appliance
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 Chapter 2, Using the Setup Wizard to Provision the
UTM in Your Network. For information about how to add and edit a
VLAN profile, including its DHCP options, see Configure a VLAN
Profile on page 96.
Assign and Manage VLAN Profiles
 To assign VLAN profiles to the LAN ports and manage VLAN profiles:
1. Select Network Config > LAN Settings. The LAN submenu tabs display, with the LAN
Setup screen in view. The following figure shows the LAN Setup screen for the UTM50
with six LAN ports, and the default VLAN profile and another VLAN profile as examples.
Note that the screens for all other UTM models (not shown in this manual) have four
LAN ports in the Default VLAN section.
