Complete Router Configuration

Before you begin to setup the PPTP Server and VPN Client you must first setup your
network. Please refer to the WZR-RS-G54 Quick Setup Guide and/or Manual to configure
the WZR-RS-G54. Once the WZR-RS-G54 is configured, record the WAN Port IP
Address, as you will need it later.
This can be found in the

‘Advanced’-> ‘Management’ ->
‘System Information’ section in the

WZR’s user interface. If you have a
dynamically assigned WAN IP
Address you may want to register
with a Dynamic DNS service so you
do not have to keep referring to the
“System Information” page to check
the WAN Port IP Address.

Dynamic DNS Services

Dynamic DNS Services provide the
ability to register a “vanity”URL, so
you do not have to remember your
public IP address. Example
http://YourName.dyndns.com
Some providers will provide this
service for free. The WZR-RS-G54
supports DynDns and TZO Dynamic
DNS services.

Refer to the WZR-RS-G54 Manual
found on the CD for more specific
information on how to configure the service.

fields. This can be the same range as the DHCP server or you can set a separate
range specifically for the VPN Clients. (This field is required.)

can be left blank.)

Allowable Address List:

This list is used to register remote IP Addresses that are authorized to connect to the
PPTP Server. These IP Addresses are required if ‘Enforce Address Restriction’was
enabled above.

Setting up your Computer as a VPN Client

A VPN Client is required to communicate with a VPN Server. You will need to install a
VPN Client on each computer that wishes to log in to the PPTP Server. You may want to
keep this setup guide handy for a quick reference to set up remote computers from a
remote location. The setup is performed once for each computer.

Windows 98SE / ME

Setting up a Windows 98SE/ME computer as a VPN Client is performed in two steps.
Step one is to setup the VPN Adapter. Step two is to configure the VPN Client. You will
need your Windows 98SE/ME CD to complete the installation.
