PPTP server setup

The SnapGear appliance includes a PPTP Server, a virtual private network server that supports up to forty simultaneous VPN tunnels (depending on your SnapGear appliance model). The SnapGear PPTP Server allows remote Windows clients to securely connect to the local network.

To setup a VPN connection:

•Enable and configure the PPTP VPN server.

•Set up VPN user accounts on the SnapGear appliance and enable the appropriate authentication security.

•Configure the VPN clients at the remote sites. The client does not require special software. The SnapGear PPTP Server supports the standard PPTP client software included with Windows 95/98, Windows ME, Windows XP, WinNT and Windows 2000. The VPN connection is simple to configure using the standard Dial-Up Networking software. The SnapGear PPTP Server is also compatible with Unix PPTP client software.

•Connect the remote VPN client.
