PPTP and L2TP
The CyberGuard SG appliance includes a PPTP and an L2TP VPN server. These allow
remote Windows clients to securely connect to the local network.
PPTP or L2TP are also commonly used to secure connections from a Guest network; see
the Guest Network section in the chapter entitled Network Setup.
PPTP VPN Server
To setup a PPTP connection from a remote Windows client to your CyberGuard SG
appliance and local network:
• Enable and configure the PPTP VPN server.
• Set up VPN user accounts on the CyberGuard SG appliance and enable the
appropriate authentication security.
• Configure the VPN clients at the remote sites. The client does not require special
software, the CyberGuard SG PPTP Server supports the standard PPTP client
software included with Windows 95/98, Windows ME, Windows XP, WinNT and
Windows 2000. The CyberGuard SG PPTP server is also compatible with Unix
PPTP client software.
• Connect the remote VPN client.
