I have a TCP service running on a PPTP client on port 4567, and the same service on another client on port 4568. They do not have public IPs. I want to connect to these services by connecting to the PPTP server on port 4567 and port 4568 from public internet. I won't be connecting as another VPN client to the PPTP server in order to access those services, any internet connected computer should be able to see those services on the PPTP server The PPTP server has a public IP. Can someone point me to any directions? Thanks in advance.
