UltraLine Home DSL Router
(
Models 7400, 7401
)
DHCP Configuration
This screen contains the settings which control how the ADSL router interacts with the local devices connected to
the router. Westell does not recommend that you change these settings. The following settings are displayed.
DHCP
DHCP Server Dynamic Host Configuration Protocol (DHCP) is an Internet
standard that allows the ADSL router to automatically assign IP
addresses to devices connected on the LAN network. It is advised
that this is enabled for Private LAN.
DHCP Start Address (If DHCP is
enabled)
This setting specifies the start of the IP address pool that the Router
uses to assign IP addresses to local devices.
DHCP End Address (If DHCP is
enabled)
This setting specifies the end address of the IP address pool used for
automatic configuration of local devices.
DHCP Lease (If DHCP is enabled) This setting specifies the DHCP lease time.
Diagnostic Log
Diagnostic Log
All
This option lists both the Connection and the System logs.
Connection This option lists all events related to connection activity (any traffic on the USB,
Ethernet, or DSL ports).
System This option lists all events related to system activity (time, errors, boot
information, etc.)
DNS Configuration
The Router has a built-in DNS server. The Router has a feature called "Dynamic DNS." When an IP address is
assigned, the Router will interrogate the new device for a machine name using several well-known networking
protocols. Any names learned will dynamically be added to the DNS server’s table of local hosts. A static host
assignment is needed only if the new device does not support any of the well-known protocols. The following
settings are displayed.

domain names.

entries.
