Tailscale. It does some UDP fuckery to bypass NAT and firewalls (most of the time) so you don’t even need to open any ports. You can run it on individual hosts to access them directly, and/or you can set it up on one device to advertise an entire subnet and have the client work like a split tunnel VPN. I don’t know about OpenWRT, but both pfSense and OpnSense have built-in Tailscale plugins.
People are freaking out about their plan to go public, but for the moment, it’s a reliable, high quality service even on the free tier.
I’ve also used Ngrok and Twingate to access my LAN from outside, but they simply use relay servers instead of Tailscale’s black magic fuckery.
