Can only Skype work over VPN?

Question

Skype

Using Skypekit, attackers find out the IP addresses of users.
I have a permanent "white" ip address.
Can I hide traffic from the Skype app behind a VPN?
How to do it? So that only vulnerable Skype sits behind vpn and this does not concern other applications in any way.

Answer 1

There is a solution for Linux , in the comments there is a link to a solution for Windows.

Answer 2

The Linux firewall can assign different routing labels to outgoing traffic by user ID and group ID, but not by process ID, unfortunately.
You need to run a proxy server on the VPN server and set it in the Skype settings so that it works only through this proxy.
If the proxy accepts connections with authorization and via https, then you can refuse vpn.

Answer 3

Look towards Proxifier

Answer 4

in the settings, make the connection only through vpn, something like that is there.
vpn will not give connection.
