PPTP VPN Connections
For an authorized user to access native IP functionality on a connected service
processor, the user needs to create a VPN connection to the OnBoard. An
authorized user can create PPTP VPN connections from Linux, Windows, or
Macintosh operating systems.
The tasks listed below must be performed by the OnBoard administrator
before any user can make a PPTP VPN connection:
• Create a VPN connection profile on the OnBoard specifying a pool of
addresses for the OnBoard and for the remote user’s computer at the other
end.
When the user creates the PPTP VPN connection, PPTP creates a new
virtual interface on the user’s host and assigns an IP address from the
OnBoard’s IP address pool to the interface. The user must use this address
when connecting to the OnBoard to enable native IP access to a device.
• Authorize the user for PPTP access and provide the user with the PPTP
password, which may be different from the password that the user uses for
accessing the OnBoard.
• Authorize the user for native IP access to a device or multiple devices.
The user must do the following tasks to enable PPTP on the user’s
workstation:
Make sure the workstation can access the OnBoard by entering the
OnBoard’s public IP address in a browser to try to bring up the Web
Manager.
• If a network or host route is needed, create a route to the private subnet
where the device resides or to the real or virtual IP address of the device.
• Make sure a PPTP client is running on the user’s workstation.
• Configure a PPTP VPN connection profile with the following information
obtained from the OnBoard administrator:
• PPTP server address = OnBoard public IP address (203.1.2.3)
• Username = OnBoard user name
• Password = PPTP password
• Make the PPTP VPN connection.
