So basically, I will be away from home for several weeks. Unfortunately, this became the perfect time for our home router to start acting out and factory resetting itself. We are awaiting a new router for replacement, but the time is tight.
My stuff is ethernetted in, so that connectivity isn’t an issue - the issue is that I couldn’t actually connect to the router to restore services even if it had internet by fixing all the settings including port forwarding.
What I would like would be the ability to have a VPN perhaps connected to my homelab, so I can hop on the router and restore the settings if this issue happens while I’m away. Any ideas?


Tailscale would work as another user said. You could run TOR too. I’ve got a TOR service that I can SSH into for “plan b” if my VPN is down. It doesn’t need port forwarding.
Tailscale or headscale if you have a VPS.
Even without a VPS Tailscale will work fine after the router resets.
Oh yes absolutely. I actually have Tailscale installed on a pfsense machine in several data centers with no up overlap and routed subnets. Works like a dream. I finally convinced work we needed to buy this. It just works too well.
But for headscale, which is essentially just a self-hosted tailscale, you should probably have a machine somewhere on the public internet to coordinate it all.
