1 Resetting the Modem
Note: Before configuring the modem using the VPN Lite utility program or advanced user setup, you
will have to reset the router to its default factory settings. All existing settings on the modem will be
lost.
Resetting to defaults also resets the modem webpage password to their default settings. (admin) and
modem IP address for the router to 10.0.0.2
To reset press the reset button at the back of the modem for about 15 seconds.

2 VPN Lite Router Setup Utility
The VPN Lite Setup Utility was developed to aid users to setup their VPN quickly and effortlessly. No
further setup will be required. The Setup Utility will configure the following for the user on the router:
•Upgrade of Firmware
•VPN Lite Connection
•Internet Connection (if necessary)
•LAN IP addresses (DHCP Server)
•NAT and Firewall settings for each connection
•Routing for each connection
Before running the VPN Lite Setup Utility, it is recommended that the user resets his router.
The Router Setup Utility can be downloaded on the VPN Lite Management website on the Downloads
Page. The Setup Utility is compressed in a zip file and only works on Windows 2000 and XP. If the
user has Windows Vista or other operating systems it is recommended that the user follows the steps
under the paragraphs for the advanced user in this document.
Once the zip file has been downloaded from the downloads page, it must be uncompressed using a
utility like WinZip or Winrar.
Run the “setup.exe” file to install the program on the PC.

Follow the Screen Prompts to complete the installation.
Select the tick box option to Launch the Utility

The utility can also be opened from the Program manager (Zyxel – Setup Device).
The first screen will give you an overview of what information will be required.
Click on “Continue” to proceed
Once the Setup Utility connects to the ADSL router then the user can configure his VPN connection
settings. The user can do this by simply adding the VPN Lite username and password that was
configured on the VPN Lite administrator Website. Please note that the username includes the realm
name as seen in the figure below. The user must also add the LAN IP Address and subnet mask also as
configured on the VPN Lite Webpage. The DHCP server on the ADSL router will use this range to
dynamically push down IP addresses in this range. The IP address must be given in a classless CIDR
format (“IP Address” / “Subnet-mask”) as seen on the VPN Lite Management Webpage (e.g
10.0.14.0/24).
Note that the IP Address for each site must fall in a different subnet.
Example: sit[email protected]te.0001 can be 10.0.1.0/24, and the subnet for [e-mail].0002 must be a
different subnet, 10.0.2.0/24. The IP Address must correspond exactly to the one configured on the
VPN Lite Management page.
If the user does not have an Internet account at this site then the Internet configuration block can be left
out. If this is the case, the Internet account will be set to login to guest@telkomadsl which will only
allow access to the www.telkom.co.za website, thus allowing the network administrator to use the VPN
Lite management without having to login to the Internet.

If the network administrator would like the computers connected to this site to have access to the
Internet as well then he must ‘check’ the tickbox next to “Do you have a Internet account?” He will
then be able to fill in an ISP username and password into the corresponding textboxes. An ADSL ISP
account is sold separately, and can be bought from any ISP.

The setup takes approximately 10 minutes due to the utility program first updating the firmware of the
modem. After the firmware update the utility will configure the router.
Restart the PC or Repair the LAN connection after the router restarted in order to change the IP address
of the PC to the range that will be used for the VPN.
