Quote from: FredFresh on March 19, 2026, 07:39:49 PMI was trying to comment each points of your configurations but it seems you deviated A LOT from the Road warrior guide:
first this https://docs.opnsense.org/manual/how-tos/wireguard-client-proton.html
later this https://docs.opnsense.org/manual/how-tos/wireguard-selective-routing.html#step-3-turn-on-wireguard
pay attention that the second page has the first part that overlap the specific Proton guide, avoid that first part
The best way is to start with the simplest configuration, once it works you can start making changes otherwise you do not know what went wrong.
Please, backup you config, clean the additional settings of the VPN (nat, firewall rules, normalization, devices...just keep peer and instance).
The guide works, what is not there shall not be changed or implemented....and do not ask to IA but here.
Once you implemented the standard configuration, if you have doubts, just write here.
I have also Proton and I can guarantee that the guide works.
Another reference point: I was having the same issues as OP and could not fix it by checking settings. I went back and deleted each entry to start fresh. It worked. I don't know what the initial problem was but now it's working.
