PPTP data stream consists of a TCP connection and maintenance of the tunnel encapsulated by the GRE tunnel data. One, TCP connections are convertible in part, directly from the source TCP port number NAT transparent translation; encapsulated by the GRE tunnel data is analyzed in the above ours, and its need to use a specific address translation NAT editor. Data in the tunnel, the tunnel is encapsulated by GRE header in the source IP address and the CALL ID field to identify the. Suppose a company now, when their internal networks also need to have more than one host as a remote PPTP client and PPTP server to establish the same connection to the tunnel, which more than one PPTP client through the NAT router, the internal private IP address will be different was converted into a public IP address. Also, because the PPTP client itself is not aware of their addresses need to be converted, they may also establish PPTP tunnel, use the same CALL ID. The consequences of this conversion is the result of NAT, multiple different from the bottom of the tunnel PPTP client data flow with the same IP address and the CALL ID.
