LAN IP Address
Selecting LAN IP Address in the “Configuring the Advanced Settings” screen generates the “LAN IP
Address” screen.
The values in the “Device IP Address” and “Device LAN Netmask” text boxes are the IP address and Subnet
mask of the Gateway as seen on the network. These values can be modified for your LAN network, but
Actiontec recommends keeping the default factory settings (
IP
address 192.168.0.1 Subnet mask
255.255.255.0).
?
Note: If the Gateway’s
LAN IP
Address is modified, ensure the
DHCP
Server range is
within the same subnet. For more information, see “DHCP Server Configuration.”
After changing settings, click Next or Back to continue, or Save and Restart to make all changes permanent.
DHCP Server
Selecting DHCP Server in the “Configuring the Advanced Settings” screen generates the “DHCP Server”
screen. The Gateway has a built-in DHCP (Dynamic Host Configuration Protocol) server that automatically
assigns a different IP address to each computer on the network, eliminating IP address conflicts.The factory
default setting is On. To disable the DHCP Server, select Off.

Actiontec strongly recommends leaving the DHCP Server option
On
. If the DHCP Server option is
Off
,
ensure the IP addresses of the networked computers are on the same subnet as the IP address of the Gateway.
For more information, see “DHCP Server Configuration.”
DHCP Server Configuration
Clicking Next in the “DHCP Server” screen (if the DHCP server is activated) generates the “DHCP Server
Configuration” screen. Change IP address range and DNS server information here.
Beginning IP Address
The “Beginning
IP
Address” is the
IP
address at which the
DHCP
server starts assigning
IP
addresses.
Actiontec recommends keeping the factory default setting (192.168.0.2).
Ending IP Address
The “Ending IP Address” is the IP Address at which the DHCP Server stops assigning IP addresses.
Actiontec recommends keeping the factory default settings (192.168.0.254).
The beginning and ending IP addresses define the IP address range of the Gateway. If the default values
are left intact, the Gateway supplies a unique IP address between 192.168.0.2 and 192.168.0.254 to each
computer on the network. Note that the first three groups of numbers of the addresses are identical; this
means they are on the same subnet. The IP address of the Gateway must be on the same subnet as the IP
address range it generates. For instance, if the Gateway’s IP address is changed to 10.33.222.1, set the
beginning IP address to 10.33.222.2, and the ending IP address to 10.33.222.254.

Default is 86400 seconds (24 hours), after which a new IP address must be released. To extend the lease
time, enter a larger number.
