NetworkActiv Listen-Listen is a special-purpose port forwarding utility. It runs as a two-sided server (female/female) where TCP clients that connect to one side can communicate with TCP clients that connect to the other side. If multiple clients are connected to one side, then all data from the opposite side is automatically replicated (syndicated) so that everyone gets a copy of each piece of data sent (from the other side). Likewise, if multiple clients are sending on one side, their data is combined and sent to the client or clients on the other side.
This system allows for easily enabling data sent from one client to be received by many other clients at the same time. The transmission is real-time, without modification or caching. All multiplexing scenarios are supported: one-to-one, one-to-many, many-to-one, and many-to-many.
Listen-Listen provides an easy-to-use graphical user interface so you can get your clients communicating in no time. Both IPv4 and IPv6 are supported. Per-client data counts are available for monitoring and troubleshooting.
