4.2.3 Dynamic IP Address Connection for WAN
A Dynamic IP Address connection configures the Router to automatically obtain its global IP address from
a DHCP server on the ISP’s network. The service provider assigns a global IP address from a pool of
addresses available to the service provider. Typically the IP address assigned has a long lease time, so it will
likely be the same address each time the Router requests an IP address.
To configure a Dynamic IP Address connection, perform the steps listed below. Some of the settings do not
need to be changed the first time the device is set up, but can be changed later if you choose. See the table
below for a description of all the settings available in this menu.

1. Under the ATM Interface settings at the top of the menu (including VPI, VCI, and Virtual Circuit)
should not be changed unless you have been instructed to change them. However, if you are instructed
to change the VPI or VCI values, type in the values assigned for your account. Leave the ATM
Interface and Virtual Circuit setting at the default (Pcv0 and Enabled) values for now. This can be
used later if you are configuring multiple virtual circuits for your ADSL service.
2. Under the Dynamic IP heading, choose the Connection Type from the pull-down menu. This defines
both the connection type and encapsulation method used for your ADSL service. The available options
are 1483 Bridged IP LLC and 1483 Bridged IP VC-Mux. If have not been provided specific information
for the Connection Type setting, leave the default setting.
3. Some ISPs record the unique MAC address of your computer’s Ethernet adapter when you first access
their network. This can prevent the Router (which has a different MAC address) from being allowed
access to the ISPs network (and the Internet). To clone the MAC address of your computer’s Ethernet
adapter, type in the MAC address in the Cloned MAC Address field and click the Clone MAC
Address button.
4. Leave the MTU value at the default setting (default = 1400) unless you have specific reasons to
change this (see table below).
