Using the Configuration Interface
19 D-Link Systems, Inc.
Advanced
The Advanced options apply to all WAN modes.
The MTU (Maximum Transmission Unit) 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.
This option is enabled by default allowing the router to select the typical
MTU settings for the selected WAN interface. If this option is unchecked, the
router will use the value assigned in the MTU field.
The WAN Port Speed is set to auto by default. If you have trouble connecting
the WAN port, you can select the connection type (10 or 100Mbps).
This option is disabled by default. By disabling the WAN ping, the router will
not respond to requests from a ping command received via the Internet.
Pinging public WAN IP addresses is a common method used by hackers to
test whether your WAN IP address is valid.
Some ISP’s may check your computer’s MAC address. Each networking
device has it’s own unique MAC address defined by the hardware
manufacturer. Some ISP’s record the MAC address of the network adapter
in the computer used to initially connect to their service. The ISP will then
only grant Internet access to requests from a computer with this particular
MAC address. The D-Link router has a different MAC address than the
computer that initially connected to the ISP. To resolve this problem, enable
this option.
When MAC Cloning is enabled, you can enter in a MAC address manually
in this field or click the Clone Your Computer’s MAC Address button.
When this button is clicked, the WAN port will use the MAC Address of the
network adapter in the computer that you are using to access the router.
