Re: PPTP over NAT The only way to do this is to get a second IP address, then set up a one-to-one static translation for it, and have all your users connect to that static IP address. Yes, multiple users will be able to connect to that one IP address, no problem there.

The Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. PPTP uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets. A PPTP tunnel is instantiated by communication to the peer on TCP port 1723. This TCP connection is then used to initiate and manage a second GRE tunnel Configure Point to Point Tunneling Protocol (PPTP) Server Dec 13, 2018 PPP, IPSec and PPTP guide - Point to Point tunneling Protocol

RFC 2637 Point-to-Point Tunneling Protocol (PPTP) July 1999 PPTP can also be used to tunnel a PPP session over an IP network. In this configuration the PPTP tunnel and the PPP session runs between the same two machines with the caller acting as a PNS. It is envisioned that there will be a many-to-many relationship between PACs and PNSs.

It is an Internet protocol commonly used in Virtual Private Network (VPN) products. Windows NT supports PPTP server, and both Windows NT and Windows 95 support PPTP client. 3. How bad is it? Very. Microsoft PPTP is very broken, and there's no real way to fix it without taking the whole thing down and starting over.

Apr 04, 2018 GlobalSSH - Free Premium PPTP The Point-to-Point Tunneling Protocol (PPTP) is an obsolete method for implementing virtual private networks. PPTP has many well known security issues. PPTP uses a TCP control channel and a Generic Routing Encapsulation tunnel to encapsulate PPP packets. Many modern VPNs use various forms of UDP for this same functionality. PPTP and L2TP - Fortinet
