Why the data captured by TupInsight are from/for my local host but other computers?
If properly installed, TupInsight (of the unlimited version) should catch data from all the computer hosts on a LAN. Since TupInsight is an eavesdropping program, whenever possible the TupInsight engine is always installed on the gateway machine (using NAT or proxy) so as to capture data from all the computer hosts on the local network. If the gateway device is a router rather than a computer, the engine should be installed on a host sharing the same network segment with the router. If only the data from/for one computer (in your case, the local host) are shown on the TupInsight console, the most probable explanation is that your local host where the TupInsight engine is installed is connected to the LAN via a switch, a device that filters and only forwards packets to the designated host. The following three schemes explain how to select a computer host for the TupInsight installation, with Fig. 3 representing the most common solution. Case one: If the networking infrastructure is a tr
