NetworkActiv PortImport - Small Screenshot


NetworkActiv PortImport provides reverse remote port forwarding, also known as reverse port tunnelling. Flowing through a single TCP connection, multiple TCP and UDP port forwards can stream simultaneously and harmoniously with PortImport. Your client's machine can remain in the comfort of its firewalled environment while you access its ports on IPv4 and IPv6 addresses. Naturally the ports accessed need not be on the machine itself but can be on any node accessible from the machine.

PortImport is a super tunnel

Initiating the tunnel is simple. The remote component, known as PortImport Daemon, is a simple native executable able to run without installation. There is no need for third-party frameworks or libraries. In fact, a settings file can be included with the executable so that the package is preconfigured to connect to your Console component immediately when run -- no interaction is required by the remote user other than downloading the two files and running the executable. Hence, the remote user need not be tech savvy.


The NetworkActiv Advantage


Although the back-end daemon is freeware, the administration console is trialware. At the time of this writing, the trial version is limited in that it cannot be installed as a service during installation and that there is a periodic nag screen that slows the forwarding until the screen is closed. Note that these limitations may change at any time without notice.

System requirements

An administrative user account is required for installation or running as a service, but running without installation should not require one.

Basic forwarding in IPv4, with TCP and UDP, was found functional on Linux (using Wine).

On Windows XP, Microsoft TCP/IP version 6 must be installed for direct IPv6 support in PortImport. Note that only the side of PortImport involved directly in the IPv6 traffic needs the protocol to be installed on the system.

25 MB of available disk space (for download, extraction, and installation).

10-50 MB of available RAM (depending on configuration).
