LAN Setup
To access the LAN Setup window, click the LAN Setup button in the Setup directory.
You can configure the LAN IP address to suit your preference. Many
users will find it convenient to use the default settings together with
DHCP service to manage the IP settings for their private network. The IP
address of the Router is the base address used for DHCP. In order to
use the Router for DHCP on your LAN, the IP address pool used for
DHCP must be compatible with the IP address of the Router. The IP
addresses available in the DHCP IP address pool will change
automatically if you change the IP address of the Router. See the next
section for information on DHCP setup.
To change the LAN Router IP Address or Subnet Mask, type in the
desired values in the Router Settings section and click the Save
Settings button. You will need to enter the new IP address to login again
to the Router’s web manager.
The DHCP server is enabled by default for the Router’s Ethernet LAN
interface. DHCP service will supply IP settings to workstations
configured to automatically obtain IP settings that are connected to the
Router though the Ethernet port. When the Router is used for DHCP it
becomes the default gateway for DHCP client connected to it. Keep in
mind that if you change the IP address of the Router the range of IP
addresses in the pool used for DHCP on the LAN will also be changed.
The IP address pool can be up to 253 IP addresses.
There are two options for DHCP service:
• You can use the Router as a DHCP server for your LAN.
• You can disable DHCP service and manually configure IP settings
for workstations.
