VLAN DHCP Options

For each VLAN, you need to specify the Dynamic Host Configuration Protocol (DHCP)
options (see Configure a VLAN Profile
for the UTM's default VLAN, or VLAN 1, is explained in
Internet and WAN Settings. This section provides further information about the DHCP
options.
DHCP Server
The default VLAN (VLAN 1) has the DHCP server option enabled by default, allowing the
UTM to assign IP, DNS server, WINS server, and default gateway addresses to all computers
connected to the UTM's LAN. The assigned default gateway address is the LAN address of
the UTM. IP addresses are assigned to the attached computers from a pool of addresses that
you need to specify. Each pool address is tested before it is assigned to avoid duplicate
addresses on the LAN. When you create a new VLAN, the DHCP server option is disabled by
default.
For most applications, the default DHCP server and TCP/IP settings of the UTM are
satisfactory.
The UTM delivers the following settings to any LAN device that requests DHCP:
• An IP address from the range that you have defined
• Subnet mask
• Gateway IP address (the UTM's LAN IP address)
• Primary DNS server (the UTM's LAN IP address)
on page 96). The configuration of the DHCP options
