IP Address
Enter the IP address for this interface. Obtain the IP address value from your
service provider or network administrator. For more information, see IP
Addresses and Subnet Masks.
Subnet Mask
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 i s used
to define the network and subnet portion of the address.
DHCP Relay
Click 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 1 DHCP
relay or 1 DHCP server per subnetwork.
Note If the router was configured to be a DHCP relay with more than one remote DHCP
server IP address, this button will be disabled.
IP Address of Remote DHCP Server
If you clicked DHCP Relay, enter the IP address of the DHCP server that will
provide addresses to devices on the LAN.
Connection: Ethernet WAN
This window lets you add an Ethernet WAN connection.
Enable PPPoE Encapsulation
Click this option if the connection must use Point-to-Point Protocol over Ethernet
(PPPoE) encapsulation. Your service provider can tell you whether the connection
uses PPPoE. When you configure a PPPoE connection, a dialer interface is
automatically created.
