D-Link DGL-4300 - Manual (Page 19)

Using the Configuration Interface
19 D-Link Systems, Inc.
All five modes have some common configuration options. The Primary and Secondary DNS Server
settings are required for Static configurations and optional for DHCP and PPPoE configurations. The
Advanced options on the following page can be modified for any of the five connection modes.
You should be able to get the
Primary DNS and Secondary DNS Servers settings from your
router configuration settings, ISP, or your network administrator. Only the primary DNS server
address is required, though it is best to have both the primary and secondary addresses.
Advanced
The Advanced options apply to all WAN modes.
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 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.
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.
