Currently I have two computers, both running Ubuntu. Both computers connect to the same ISP, but with one I use a VPN service. For reasons not relevant to this question, I am considering getting rid of the VPN computer and consolidating all my tasks to the other computer. However, I would still like to use the VPN service for some programs, but not all.

With my current set up, on the computer I am keeping, I can click on the network icon in my panel (Gnome Classic) and toggle my VPN on and off. However, this is global and affects all internet connections from all programs. This is not ideal. The VPN service, while offering privacy and access to services otherwise unavailable in my area, is slower than my non-VPN connection.

What I'm after is a situation like this: I'm using Firefox, and I'm also using Clementine for streaming radio. I then want to open Chrome and have Chrome access the internet via the VPN. Ideally, Chrome is set up so that it automatically uses the VPN without me having to turn it on and off. However, I want Firefox and Clementine to continue accessing the net directly, not switch over to the VPN service.

Is this possible? If so, how?
