In addition, I would also install PiVPN (an OpenVPN server) on the same Raspi and an OpenVPN client on the smartphones.
This kills 3-4 birds with one stone:
You have a permanent, protected VPN connection to your home network, which has the following advantages:
- You always benefit from the Pi-hole filter even when you are away from home
- You can also use private landline telephony externally with the Swisscom Home app
- you can watch Swisscom TV live from abroad and not just replay/recordings
- You have access to your home network and its participants at any time
Uncle Google knows how to easily set up PiVPN
