PortImport

PortImport provides remote port reverse forwarding, also known as reverse port tunnelling. It supports both TCP and UDP ports and even multiple connections in addition to supporting simultaneous and harmonic streaming. This allows the client PC to remain in the safety of the firewall environment while you can use the IPv4 and IPv6 address ports. The application supports real-time logging and connection logging, makes do with a single TCP connection between the client and the console, and can be deployed as a Windows service.
