What I use...
I haven't tried it with other software but here's my solution for remote scanning.
I have mostly GRE produced scanners so I can start there. My technique requires a second computer to be attached to the radio and be permanently connected (at least when I want to monitor).
For the Pro-106, 197, PSR-500, & 600, I use Win500 to manage the radios. It also allows logging, recording, and remote monitoring and control. I run the Win500 program software on a small "barebones" computer which is always on and constantly logging/recording various frequencies. I am also able to run/control several radios simultaneously with this one computer.
When I am away from the radio setup, I can use it in conjunction with the Win500 client software (included in the original purchase and installed on a laptop) to listen across the internet or across my home network. In the client, you enter the IP address and the port number assigned to the program on the computer controlling the radio. You can enter a local IP address across your home network or the ip address of your home connection when you are across the internet.
I looked at one of your old posts and it appears you're trying to control a BCT15X. I don't have any experience with FreeScan

but it does allow "remote control" according to the site. I don't know if that includes control across IP but it is free to use.
I'm pretty sure ProScan
ProScan
will do it the same as Win500 (which is only for GRE produced radios) but it costs $50. It does offer a free 30 day trial to see if it works for what you want and there is a client free to download onto your laptop.
Not sure if this really answers your question but it is the setup I use to do the same thing that I believe you are trying to set up.
You will be able to find more about these programs in this forum.
Let us know how it's going
