5. Click Apply to save your settings. Click Test to verify that the connection is active.
Note: At this point in the configuration process, you should have an active
connection to the Internet through the Ethernet connection to an external
broadband modem.

Configuring Advanced Options for the ISP Connections

You can change the values of several Advanced WAN options including the MTU size, Ethernet
WAN port speed, and the MAC (Media Access Control) address of your WAN port.
These Advanced Options are available for both ADSL and Ethernet connections.
• MTU Size. The normal MTU value for most networks is 1500 Bytes, or 1492 for PPPoE
connections. For some ISPs, you may need to reduce the MTU size. However, this is rarely
required and should not be attempted unless you are sure it is necessary for your ISP
connection.
• Port Speed (Ethernet only). Usually, the DGFV338 can automatically determine the
connection speed of the device connected to the 10/100 WAN port. If you cannot establish an
Internet connection and the Internet LED blinks continuously, manually select the port speed.
If the Ethernet port on your broadband modem supports 100BaseT, select 100M; otherwise,
select 10M. Use the half-duplex settings unless you are sure your broadband modem supports
full duplex.
• Router MAC Address. Each computer or router on your network has a unique 32-bit local
Ethernet address, known as the Media Access Control (MAC) address. In most cases the
default (Use Default Address) will suffice. If your ISP requires MAC authentication and
expects a specific MAC address, then select either:
– Use This Computer's MAC address, where the DGFV338 will use the MAC address of the
computer you are now using, or
– Use This MAC Address, where you manually enter the MAC address that your ISP
expects. The format is 12 hexadecimal digits, such as 01:23:45:67:89:AB.

Configuring the ADSL Settings

If you set up an ADSL connection, in addition to the Advanced ADSL settings, there are some
additional specific ADSL settings that also can be configured. These include: Multiplexing
Method, VPI and VCI.
