SnapGear 1.7.8 - Manual (Page 81)

To determine the current SnapGear appliance’s PPTP server IP address, select
Diagnostics from the System menu in the main menu bar. The IP address is displayed
in the VPN field. Your remote users must know this PPTP IP address to setup a VPN
tunnel to the SnapGear appliance.
Check that the remote PC has a modem installed and that you have a local ISP account,
(i.e. an ISP phone number and a username and password to log in to the ISP). Although
users are often connected to the Internet using a dial-out modem, VPN connection can
also be set up using a cable modem, ADSL, ISDN or other Internet link.
Ensure that both the VPN and Dial Up Networking (DUN) software is installed on the
remote PC. If necessary, install the Microsoft DUN update (available on the SnapGear
Installation CD) and VPN Client update.
To create a VPN connection across the Internet, you must set up two networking
connections. One connection is for the Internet access provider, and the other connection
is for the VPN tunnel to your office network. Verify that a networking connection is
established for the link to your local ISP.
Set up a new connection for the VPN connection. Your SnapGear appliance’s PPTP
server will operate with the standard Windows PPTP clients in all versions of Windows.
The following sections provide details for client setup in Windows 95/98, Windows NT,
and Windows 2000. Setup instructions for Windows ME and Windows XP can be
deduced from this information and the Microsoft Windows documentation.
