My dog absolutely hates being outside in the yard, but she loves walks and hikes. Unfortunately the nearest place that’s safe for us to walk is a long car ride away because I live in a somewhat rural area. So she only ever gets these on weekends when I’m able to dedicate several hours to it. If I were to live in a city she’d be getting a ton more stimulation daily.

Sorry, I can’t get the answer to that on iPhone.

Yeah, that's originally why I had it set up this way because I was somewhere where I wasn't able to open any ports.

It’s a bit of a janky solution, but I’m just running an openvpn server on the lowest tier vps which my home server auto-connects to on boot. From there it’s just iptables rules to reroute the external traffic through the VPN. I’ve also used it to proxy Minecraft servers and a few other things.
