DGFV338 ProSafe Wireless ADSL Modem VPN Firewall Router Reference Manual

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, your router can automatically determine the connection speed of the 10/100 port. If you cannot establish an Internet connection and the Internet LED blinks continuously, manually select the port speed.

If you know your Ethernet port on your broadband modem supports 100BaseT, select 100M; otherwise, select 10M. Use the half-duplex settings unless you are sure you need 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, then select either:

Use This Computer’s MAC address, where the router 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 XX:XX:XX:XX:XX:XX.
