Dynamic IP Address (DHCP) Configuration
The WAN interface can be configured as a DHCP Client in which the ISP provides
the IP address to the device. This is also known as Dynamic IP.
Select the

from the

drop-down
list.
Host Name
: Specify a host name to define your system or connection.
Use Unicasting
: This option is normally turned off, and should remain off as
long as the WAN-side DHCP server correctly provides an IP address to the
router. However, if the router cannot obtain an IP address from the DHCP
server, the DHCP server may be one that works better with unicast responses.
In this case, turn the Unicasting option on, and observe whether the router
can obtain an IP address. In this mode, the router accepts unicast responses
from the DHCP server instead of broadcast responses.
Primary / Secondary DNS Address:
Specify the primary and secondary IP
address, which are assigned by your ISP.
MTU
: The Maximum Transmission Unit (MTU) 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
