TwoBind

TwoBind provides a straightforward port forwarding solution for all network administrators, allowing them to forward data received by a port to other clients connected to another port.

Its major advantage is that it can listen to two different TCP ports, making it possible to automatically replicate data. To be more specific, all the clients connected to one side will receive data transmitted by clients connected to the other side through port forwarding.

What's more, it enables network administrators to avoid working with the command prompt, displaying all the configuration options within a user-friendly interface. All the connected clients are shown within the main window, along with the connection duration, used port and the amount of produced data.

TwoBind features a simple GUI layout, where all the functions are one-click away. You can easily set the address and port number to listen to for both sides. The TCP Nagle algorithm can be disabled thanks to the 'TCP NoDelay' option, which results in a rather lower sending latency time. Note that this might affect bandwidth usage.

Data transmitted via TwoBind is not cached or stored, but transmitted in real time. As such, a newly connected client can only receive data that was sent after its connection time.

TwoBind supports one-to-multiple and multiple-to-one data sending, providing a reliable port forwarding solution for advanced users. This means that data can be transmitted from a single client to a large number of connected peers from the opposite side and viceversa.

With just a click, the administrator can disconnect a client, if needed. The application is configured to remember all settings, so starting a new connection is done in seconds.
