PPTP range VPN
PPTP
FortiGate units support PPTP to tunnel PPP traffic between two VPN peers. Windows
or Linux PPTP clients can establish a PPTP tunnel with a FortiGate unit that has been
configured to act as a PPTP server. As an alternative, you can configure the FortiGate
unit to forward PPTP packets to a PPTP server on the network behind the FortiGate
unit.
For information about how to perform these tasks, see “PPTP configuration
procedures” on page 268.
To enable PPTP and specify the PPTP address range
1 Go to VPN > PPTP > PPTP Range.
2 Enable PPTP and specify the address range.
PPTP range
The PPTP address range is the range of addresses reserved for remote PPTP clients.
When the remote PPTP client connects, the FortiGate unit assigns an IP address from
a reserved range of IP addresses to the client PPTP interface. The PPTP client uses
the assigned IP address as its source address for the duration of the connection.
