Static IP Address Configuration

The WAN interface can be configured as Static IP address. In this type of

connection, your ISP provides you with a dedicated IP address (which does not

change as DHCP).

Select

Static IP

from the

My Internet Connection

drop-down list.

°

IP Address:

Specify the IP address for this device, which is assigned by your

ISP.

°

Subnet Mask:

Specify the subnet mask for this IP address, which is assigned

by your ISP.

°

Default Gateway:

Specify the IP address of the default gateway, which is

assigned by your ISP.

°

Primary / Secondary DNS Address:

Specify the primary and secondary IP

address, which is assigned by your ISP.

MTU

: The Maximum Transmission Unit (MTU) is a parameter that determines

the largest packet size (in bytes) that the router will send to the WAN. If LAN

devices send larger packets, the router will break them into smaller packets.

Ideally, you should set this to match the MTU of the connection to your ISP.

Typical values are 1500 bytes for an Ethernet connection and 1492 bytes for

a PPPoE connection. If the router's MTU is set too high, packets will be

fragmented downstream. If the router's MTU is set too low, the router will

fragment packets unnecessarily and in extreme cases may be unable to

establish some connections. In either case, network performance can suffer.

°

MAC Address

: If you need to change the MAC address of the router's WAN-

side Ethernet interface, either type in an alternate MAC address (for example,

the MAC address of the router initially connected to the ISP) or click on

Dynamic IP Address (DHCP) Configuration

The WAN interface can be configured as a DHCP Client in which the ISP provides

the IP address to the device. This is also known as Dynamic IP.

Select the

Dynamic IP (DHCP)

from the

My Internet Connection

drop-down

list.

°

Host Name

: Specify a host name to define your system or connection.

°

Use Unicasting

: This option is normally turned off, and should remain off as

long as the WAN-side DHCP server correctly provides an IP address to the

router. However, if the router cannot obtain an IP address from the DHCP

server, the DHCP server may be one that works better with unicast

responses. In this case, turn the Unicasting option on, and observe whether

the router can obtain an IP address. In this mode, the router accepts unicast

responses from the DHCP server instead of broadcast responses.
