SSH through VPN [closed]

        my company provides a VPN connection to access internal systems.<br />

The internal systems only allow access from the IP range of the VPN.

When I try to connect via ssh to an internal system, it fails.
After some testing, I figured out that ssh is not using the VPN connection but my public IP address from my ISP. Therefore no connection to the systems…

Question:
How can I configure ssh to use the VPN connection?
And how can I use this using the ssh-extension for VScode?

OS of my Laptop is win10.
