Dynamic IP Address
Selecting this option in the WAN Settings will change your screen to look like the one seen below.
Users choosing this option should have software located on their computer or other networking device
to establish a connection between you and your ISP. The Connection Type is chosen by using the pull-
down menu. The two choices available to the user here are 1483 Bridged IP LLC and 1483 Bridged
IP Vc-Mux, and this correct choice should also be provided to you by your ISP. The Cloned MAC
Address field is used to copy the MAC Address of your Ethernet Adapter to the router. Simply enter
the MAC Address into the space provided and click the Clone Mac Address button. The Maximum
Transmission Unit (MTU) is a link layer restriction on the maximum number of bytes of data in a
single transmission. The default size is 1400 bytes per packet. NAT improves network security in
effect by hiding the private network behind one global and visible IP address. NAT address mapping
can also be used to link two IP domains via a LAN-to-LAN connection. To enable NAT on the Router,
use the pull-down menu and select Enabled. The Firewall allows the Router to enforce policies to
protect against certain kinds of attacks. To enable the firewall on the Router, use the pull-down menu
and select Enabled.
