An rpi might work for your computer issues.

No. I do that for my job and wouldn’t do it for personal use. HA/redundancy/security is too expensive.

Consider splitting your compute and storage. A dedicated NAS and the connect your compute to it using nfs or iSCSI.

At the enterprise level an Opengear appliance fixes this.

Tripplite PDUs have an option to perform a ping test against an ip, and if it stops responding it can power cycle the outlet of your choice.

If you want to get fancy you can advertise routes from two routers into your L3 switch and if a route goes down your switch will use the backup.

VMs are managed by you. You’re responsible for dealing with prerequisites, updates, security.

Docker is a dev stating “works on my machine” and giving you a copy of their machine.

You can run docker within proxmox, and doing so gives you the ability to run containers in addition to VMs.

There are advantages and disadvantages to both.

If only that were true.

Real email security gateways cost money. There’s no good way to deal with it at small scale.

It’s not worth it but some people don’t mind the cost.

This could be easily solved with domain name and certificates

Insulation.

Or replace the drives.

NFS works, but http was designed for shitty internet. Keep that in mind. Owncloud or similar might be a good idea.

LAN or internet?

Https is king for internet protocols.

There were a lot more during one of the big Reddit migrations but they don’t work.

Communities need engagement and you don’t get that with bot cross posts.

It’s not odd. You’ll need to build the 3 VMs if you want to run Kubernetes and not destroy your existing hypervisor.

In windows you may need to add an ifilter. Adobe’s is pretty good. Then windows search will be able to search contents.

The answer here is still a single vpn, and Tailscale makes this even easier.

What you’re describing is overly complex routing, and split DNS.

Join all clients to a single network.

From the diagram you just want to put everything within a vpn so they are on the same network.

You can choose whatever vpn solution you want but I like Tailscale since you don’t need to set up any inbound nat or firewall.

From the diagram it looks like you want your outside clients to use vpn as well.

Yes.

Otherwise, just open up ports on your network firewall and set up DNS to point to your external ip.

There might be a way to do this with cloudfare that is more secure.

Edit: you might want to create a network diagram to help explain what you have and what you want to do. The way you describe the problem is confusing.

Install Tailscale on your vps and your homelab server.

Share the Tailscale dns of your server with guests.

Use your vps as your exit node.
