Section 3 - Configuration
My Internet Connection is: Dynamic IP (DHCP)
The default WAN configuration for this router is Dynamic IP (DHCP). This
option allows the router to obtain an IP address automatically from the
device that is connected to the Internet port.
Note:
If you’re not sure about the type of Internet Connection you have,
please contact your Internet Service Provider (ISP) for assistance.
After selecting Dynamic IP, the following parameters will be available for
configuration:
Host Name:
The Host Name is optional but may be
required by some ISPs. Leave blank if you
are not sure.
Use Unicasting:
Tick this option if you ISP uses the unicast
method to provide IP addresses.
Primary DNS:
Enter the Primary DNS IP address used
here.
Secondary DNS:
Enter the Secondary DNS IP address
used here. This field is normally optional.
Only one DNS address is required for a
functional Internet connection, but using
a second DNS address provides more
stability.
MTU:
Maximum Transmission Unit - you may need to change the MTU for optimal performance with your specific ISP.
1500 is the default MTU.
MAC Address:
The default MAC Address is set to the Internet port’s physical interface MAC address on the router. It is not recom-
mended that you change the default MAC address unless required by your ISP. You can use the
Clone Your PC’s
MAC Address
button to replace the Internet port’s MAC address with the MAC address of your Ethernet card.
