To configure a Dynamic IP Address connection for the WAN, follow these steps:
1.
Choose the Dynamic IP Address option from the WAN Setting pull-down menu.
2.
Under the ATM VC Setting at the top of the window 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 PVC 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. For more information on ATM VC Settings, see the table on
page 46 below.
3.
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.
4.
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.
5.
Leave the MTU value at the default setting (default = 1400) unless you have specific reasons to
change this (see table below).
6.
NAT should remain Enabled. If you disable NAT, you will not be able to use more than one
computer for Internet connections. NAT is enabled and disabled system-wide, therefore if you are
using multiple virtual connections, NAT will disabled on all connections.
7.
The Firewall should remain enabled for most users. If you choose to disable this you will not be
able to use the features configured in the Firewall Configuration and Filters windows located in
the Advanced directory. See the next chapter for more details on these windows.
8.
Point-to-Point Tunneling Protocol is a pass-through mechanism that allows packets to pass
through the Router so that it effectively functions as a bridge. Check Enable PPTP and enter the
required information in the ServerIP/Name, Route Target, Route Mask, PPTP Account, PPTP
Password, and MPPE Encryption fields. A table on page 47 provides a summary of the
parameters used to configure PPTP connections.
9.
Most users will not need to change ATM settings. If this is the first time you are setting up the
ADSL connection it is recommended that you leave the Service Category settings at the default
values until you have established the connection. See the table on page 44 for a description of the
parameters available for ATM traffic shaping.
10.
When you are satisfied that all the WAN settings are configured correctly, click on the Apply
button.
11.
The new settings must be saved and the Router must be restarted for the settings to go into
effect. To save and reboot the Router, click on the Tools directory tab and then click the System
button. In the System Settings window, click the Save and Reboot button under Save Settings
and Reboot the System.
12.
Click OK when the following "Save and restart?" dialog box opens.
13.
The Router will save the new settings and restart. Upon restarting the Router will automatically
establish the WAN connection.
