I am using the MacOS client of PIA in tandem with Little Snitch to monitor network activity, but within this question, I am curious how VPN clients work generally.
For privacy and security I, like most VPN users, would like all of my traffic to be routed through my VPN. While my VPN is connected and killswitch is activated, I am seeing many applications with incoming/outgoing traffic in addition to pia_openvpn_client (examining in little snitch network monitor).
My understanding of how VPN clients/tunneling works: The VPN takes every IP packet you would've sent and wrap it up into an IP packet addressed to the VPN server so that it appears to come from a distant machine. Sort of like mailing a pre-addressed envelope to your friend to send on your behalf.
If this is the case, shouldn't all of the traffic on my computer be from the VPN client? I know I can navigate Chrome to a website which tells me that Chrome's traffic is coming from a known VPN IP address, but how can I verify that ALL of my computer's traffic is being tunneled?
Thank you all in advance :)
