Using the Configuration Menu (continued)
Home > WAN > Dynamic IP Address
Dynamic
IP Address-
Most Cable modem users will select this option to obtain an IP
Address automatically from their ISP (Internet Service Pro-
vider).
Host Name- This is optional, but may be required by some ISPs. The host
name is the device name of the Router.
MAC Address- The default MAC Address is set to the WAN’s physical inter-
face MAC address on the Router.
Clone
MAC Address- Copy the MAC address of the Ethernet card installed by your ISP,
and replace the WAN MAC address with this Ethernet card MAC
address. It is not recommended that you change the default MAC
address unless required by your ISP.
MTU- Enter an MTU value only if required by your ISP. Otherwise,
leave this section to its default setting of 1500. (MTU is short
for Maximum Transfer Unit. Messages longer than the MTU
will be divided into smaller units for transmission).
Primary/Secondary
DNS-
Enter a DNS Address if you do not wish to use the one provided
by your ISP. (DNS is short for Domain Name System. It trans-
lates domain names into IP Addresses).
