Host Name and Doma±n Name
These fields allow you
to supply a host and domain name for the Gateway.
Some ISPs, usually cable ISPs, require these names as
identification. You may have to check with your ISP to see
if your broadband Internet service has been configured
with a host and domain name. In most cases, leaving these
fields blank will work.
MTU
MTU is the Maximum Transmission Unit. It specifies
the largest packet size permitted for Internet transmission.
Select
Manual
if you want to manually enter the largest
packet size that is transmitted. To have the Gateway select
the best MTU for your Internet connection, keep the
default,
Auto
.
S±ze
When Manual is selected in the
MTU
field, this option
is enabled. Leave this value in the 1200 to 1500 range. The
default, MTU is configured automatically.

Network Address Server Settings (DHCP)
The settings allow you to configure the Gateway’s Dynamic
Host Configuration Protocol (DHCP) server function. The
Gateway can be used as a DHCP server for your network.
A DHCP server automatically assigns an IP address to each
computer on your network. If you choose to enable the
Gateway’s DHCP server option, make sure there is no
other DHCP server on your network.

DHCP Server
A Dynamic Host Configuration Protocol
(DHCP) server automatically assigns an IP address to each
computer on your network for you. Unless you already

mode. (This setting is not available for all encapsulation
types.)
DHCP Relay Server IP
Enter the DHCP server IP address
to relay DHCP requests from the local network when the
Gateway is in DHCP Relay mode.
Start±ng IP Address
Enter a value for the DHCP server

192.168.1.253. The default is
²92.²68.².²00
.
