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!

I remember a TV station I worked at, that had a lot of good redundancies with 3 redundant UPSs that could keep a bunch of equipment on air until the big generator took over, one day had the UPS controller die and took all 3 UPSs out. I think it took the engineers a couple days to get everything back up and running.
