Table 4-1. VLAN Profile Settings
Setting Description (or Subfield and Description)
VLAN Profile
Profile Name Enter a unique name for the VLAN profile.
Note: You can also change the profile name of the default VLAN.
VLAN ID Enter a unique ID number for the VLAN profile. No two VLAN can have the same
VLAN ID number.
Note: You can enter VLAN IDs from 2 to 4093. VLAN ID 1 is reserved for the
default VLAN; VLAN ID 4094 is reserved for the DMZ interface.
Port Membership
Port 1
Port 2
Port 3
Port 4 / DMZ
Select one, several, or all port checkboxes to make the port(s) member of this
VLAN.
Note: A port that is defined as a member of a VLAN profile can send and receive
data frames that are tagged with the VLAN ID.
LAN TCP/IP Setup
IP Address Enter the IP address of the UTM (the factory default is 192.168.1.1).
Note: Always make sure that the LAN port IP address and DMZ port IP address
are in different subnets.
Note: If you change the LAN IP address of the VLAN while being connected
through the browser to the VLAN, you will be disconnected. You must then open
a new connection to the new IP address and log in again. For example, if you
change the default IP address 192.168.1.1 to 10.0.0.1, you must now enter
https://10.0.0.1 in your browser to reconnect to the Web Management Interface.
Subnet Mask Enter the IP subnet mask. The subnet mask specifies the network number portion
of an IP address. Based on the IP address that you assign, the UTM
automatically calculates the subnet mask. Unless you are implementing
subnetting, use 255.255.255.0 as the subnet mask (computed by the UTM).
DHCP
Disable DHCP
Server
If another device on your network is the DHCP server for the VLAN, or if you will
manually configure the network settings of all of your computers, select the
Disable DHCP Server radio button to disable the DHCP server. This is the
default setting.
Enable DHCP
Server
Select the Enable DHCP Server radio button to enable the UTM to function as a
Dynamic Host Configuration Protocol (DHCP) server, providing TCP/IP
configuration for all computers connected to the VLAN. Enter the following
settings:
Domain Name This is optional. Enter the domain name of the UTM.
