Help with reverse proxy architecture (discuss.tchncs.de)

In my home network, I'm currently hosting a public facing service and a number of private services (on their own subdomain resolved on my local DNS), all behind a reverse proxy acting as a "bouncer" that serves the public service on a subdomain on a port forward.

I am in the process of moving the network behind a hardware firewall and separating the network out and would like to move the reverse proxy into its own VLAN (DMZ). My initial plan was to host reverse proxy + authentication service in a VM in the DMZ, with firewall allow rules only port 80 to the services on my LAN and everything else blocked.

On closer look, this now seems like a single point of failure that could expose private services if something goes wrong with the reverse proxy. Alternatively, I could have a reverse proxy in the DMZ only for the public service and another reverse proxy on the LAN for internal services.

What is everyone doing in this situation? What are best practices? Thanks a bunch, as always!

If you are running your servies in a single VM in your DMZ then that is your point of failure. You could spin up 2 micro VMs and run something like Docker swarm to make sure there are 2 trafik proxies running.

The services run on a separate box; yet to be decided on which VLAN I put it. I was not planning to have it in the DMZ but to create ingress firewall rules from the DMZ.
