The device can also act as a DHCP relay, escalating DHCP responsibilities to a WAN
DHCP server. In this case, the device acts merely as a router, while its LAN hosts receive
their IP addresses from a DHCP server on the WAN. With the device's optional Zero
Configuration Technology feature, the IP Auto Detection method detects statically-defined
IP addresses in addition to the device's DHCP clients. It learns all the IP addresses on the
LAN, and integrates the collected information with the database of the DHCP server. This
allows the DHCP server to issue valid leases, thus avoiding conflicting IP addresses used
by other computers in the network.

To configure DHCP:
1. Click the DHCP Server item ( Configuration tab > Data Settings menu > Services
submenu > DHCP Server page item); the following page appears:
Figure 3-93: Configuring DHCP Server
The page displays a summary of the services currently being provided by the DHCP
server.
Note: If a device is listed as "Disabled" in the 'Service' column, then DHCP services
are not being provided to hosts connected to the network through that device.
This means that the device does not assign IP addresses to these computers,
which is useful if you wish to work with static IP addresses only.
2. Click the Edit icon corresponding to the required device; the following page appears:
Figure 3-94: Defining IP Distribution Type
3. From the 'IP Address Distribution' drop-down list, choose either 'DHCP Server', 'DHCP
Relay' (or 'Disabled' if you want to disable DHCP).
4. If you selected 'DHCP Server', the following fields appear:
