    Preferably can be installed on W10 without using VM. I googled around and i cant find any that can be installed on windows. like Pfsense, untangle, opnsense, etc all needs VM.

    thank you

    Sorry forgot to post my result

    1. Resmon.exe can list the connection to what domains or ip address
    2. In the end I use simple firewall

    Wireshark has been around forever and has a Windows version. I've not used Wireshark for quite a few years but was a heavy user at one time. Of course, the downside to any monitoring tool running in the same OS as the program you wish to monitor, is if that program is deliberately trying to conceal it's network activity, there are ways to do this. Applications do not have to use the OS TCP/IP stack.

    If this is the situation then an external device is what you may need. Some routers let you monitor traffic, otherwise a cheap RaspberryPi as a router/gateway monitor can be setup inexpensively.
