What are the limitations of PPTP in pfSense


PPTP in general has many limitations, especially from a security standpoint. It should not be used no matter how strongly a client pushes to have it enabled.

There are limitations of PPTP in pfSense® software, due to limitations in the NAT capabilities of pf.

Only one client can connect to a given PPTP server on the Internet simultaneously. 10 clients can connect to 10 different servers, but only a single simultaneous connection can exist to a single remote server.
