I followed this guide (https://docs.opnsense.org/manual/how-tos/wireguard-client-proton.html) on how to set up VPN, but all of my traffic from the affected machines is being served by the firewall instead of being sent over the VPN tunnel. I'm hoping someone's seen this before and is able to just say "ah yes, go here and check this box" or something..
ping google.com

I got OpenVPN working, so I have a working solution; this is just weird now.
