Reverse Proxy: a single point of failure in my lab (lemmy.dbzer0.com)

So, just for the sake of it I've been trying to get my lab to be HA -or as HA as a small homelab can be-

My current set up is a follows:

3 proxmox servers with some Debian VMs, the VMs run docker swarm

A NAS, with Truenas

ISProuter -> OpenWRTRouter -> VM [Port fowards 80/443]

This works like a charm when I am in my LAN, but when I access from outside, if the VM that has 80/443 port forwarded to is down (which it never is) I'd loose connectivity.

I have now idea how to solve this little problem in a efficient way, maybe a reverse proxy running on my OpenWRT? (Which'd only move the point of failure to my router, but if my router goes down is gameover already anyways) has anyone attempted this?

Any opinions/ideas?

Update:

Solved! I moved my traefik data to a NFS share in my NAS, replicated the container across all manager nodes and then installed keepalived and now float a VIP between them.

Works like a charm and it was super easy to set up, literally 3 ansible tasks and 1 jinja template and you are done.

Thanks to all of ya!

Our new dog chewed up the Ethernet cable

Ugh! I had some of the same issues a while ago with a Jack Russell I adopted. Cool dog, high octane energy, eager to learn new things. Since he was teething, everything became a chew toy regardless of the mountain of chew toys I had already provided. USB cables, Ethernet cables, power cords, I've replaced a bunch. Thing about a Jack Russell is you can teach them anything and they are eager to learn and please, however, if they pick up a bad habit, it's hard to break them of that. He doesn't chew anything any more, but there for a stint, he was hell on wheels.
