(By default, routers expose a limited set of common ports, and are manually configured to use other ports for specific purposes.) Port ForwardingĮxposing a port (or a range of ports) so an external network can communicate with the port used by internal application is called “port forwarding.” It cannot, however, automatically configure the router to allow traffic from the WAN to reach that port. The NDI Bridge Host finds your public IP address automatically, and listens for traffic arriving at the port you specify in its configuration app. ![]() ![]() If the network router doesn’t expose a port, no-one can connect to it. Likewise, your network router exposes certain ports for external access. Your firm provides a list of extension numbers, each matching one phone. On a wide area network (WAN) like the Internet, the ‘public IP number’ corresponds to the main telephone number. This is much like an office with one main telephone number, but many extensions. Connecting to a local application from an external network requires targeting the correct port, and that your network router is set up to accept traffic at that port. To extend beyond the local network, applications (such as NDI Bridge) use network communication ports. In more complex cases, though, another factor may need your attention. NDI ® greatly simplifies sending high quality, low–latency video across your network. ![]()
