Static IP Address
If you selected Static IP address, enter that IP address in this field.
Subnet Mask
Enter the subnet mask in this field, or select the number of subnet bits from the
field on the right. The subnet mask tells the router which bits of the IP address
designate the network address and which bits designate the host address.
Use this window to configure the
interface that you want to use as a LAN interface.
Enter the IP address for this interface. Obtain the IP address value from your
service provider or network administrator. For more information, refer to
Addresses and Subnet
Enter the subnet mask. Obtain this value from your network administrator. The
subnet mask enables the router to determine how much of the IP address is used
to define the network and subnet portion of the address.
Click this button to enable the router to act as a DHCP relay. A device acting as a
DHCP relay forwards DHCP requests to a DHCP server. When a device needs to
have an IP address dynamically assigned, it broadcasts a DHCP request. A DHCP
server replies to this request with an IP address. You can have a maximum of one
DHCP relay or one DHCP server per subnetwork.
If the router has been previously configured to be a DHCP relay and is configured
to have more than one remote DHCP server IP address, this button will be
disabled.
