I have a pi 3 B+ running as an LTE to WiFi gateway. I'm not using the native WiFi but the ethernet is connected to an openwrt router.

Since I had ram to spare it also does:

- dhcp

- caching DNS + filtering

- Mqtt server

- GPS-based NTP server

- Openvpn server to my nas (at a different location) and vps
