VLAN DHCP Options
For each VLAN, you need to specify the Dynamic Host Configuration Protocol (DHCP)
options (see Configure a VLAN Profile on page 83). The configuration of the DHCP options
for the VPN firewall’s default VLAN, or VLAN 1, is explained in Configure the IPv4 Internet
Connection and WAN Settings on page 28. 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
VPN firewall to assign IP, DNS server, WINS server, and default gateway addresses to all
computers connected to the VPN firewall’s LAN. The assigned default gateway address is
the LAN address of the VPN firewall. 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 VPN firewall are
satisfactory.
The VPN firewall delivers the following settings to any LAN device that requests DHCP:
An IP add
ress from the range that you have defined
Subnet
mask
Ga
teway IP address (the VPN firewall’s LAN IP address)
Primary DNS server (th
e VPN firewall’s LAN IP address)
WINS server (if you entered a WINS server
address in the DHCP Setup screen)
Lease time (th
e date obtained and the duration of the lease)
