Assigning the IP using DHCP protocol
Many networks use DHCP (Dynamic Host Configuration
Protocol) or its predecessor BOOTP described in the following
section for centralized and dynamic assignment of the network
parameters. DHCP protocol is activated by the factory default
settings, so that in network environments dynamic IP
assignment is sufficient for connecting the LAN-Modem to the
network. The following parameters can be assigned using
DHCP:
• IP address
• Subnet mask
• Gateway address
• Lease time

To prevent unintended address assignments or changes,
we recommend deactivating the DHCP and BOOTP/RARP
protocols if they are not expressly used in the respective
network environment. LAN-Modems with incorrectly assigned IP
addresses can be easily found after the fact using the scan
function of the WuTility management tool and reconfigured.
2.3.1 Activating/Deactivating DHCP
The factory default setting is for DHCP protocol active. To
deactivate it or to enable it again later, use one of the following
options.
•
Management-Tool WuTility
Select the desired LAN-Modem in the device list and click
on the IP Address button. In the following dialog box enter
the desired option DHCP, BOOTP or Static. Clicking on
Continue then sends the new configuration data to the LAN-
Modem.
