I was wondering if it was (or will be) possible to create multiple connexion to the VPN and mange which program uses which connection ?
myScript -> VPN 1
The rest of my computer -> VPN 2
It's not possible to create multiple VPN connections for specific programs, but you can route apps and websites outside the VPN connection using the Split Tunneling feature. Although this may not be relevant for your question, it might be of interest. Split Tunneling allows you to route any website or app outside the VPN connection, to access the Internet directly. This feature is available for Windows, Mac, Android, and iOS.
