@incognet I'm testing WG Tunnel, https://wgtunnel.com/ but I'm currently only testing it with Wireguard, as when I looked into setting up AmneziaWG I decided I wanted to give it another 6 months and check back if there was a more mature way to install a minimal server - currently I use PiVPN on a VPS as my endpoint, which is lighter weight than the existing AmneziaWG solutions.
I *just* found WG Tunnel like 2 days ago when looking for Android clients with a "trusted network" feature.
for devices other than my phone, I'm using GL.iNet routers and vanilla OpenWrt routers, all with vanilla WireGuard at the moment. I'm interested in switching to AmneziaWG as it matures. and GL.iNet is alpha testing it in their firmware on one or two of their router models now.
