I will be setting up some servers for which I need a fast internet connection and one IPv4 per VM. I’m looking at having ~10 VM’s for now, I’ll be taking them to Hetzner.
This stuff is quite new to me, I’m starting a CCNA course later this year but for the moment I’ve got some questions:
- Do I have enough with 1 managed switch to route the traffic & IP addresses to the machines? I run up to 4 VM’s per machine via Proxmox.
- Or should I consider something like a router with 1:1 NAT mapping? This seems easiest for me.
- Do I need a hardware firewall?
I would like to run as little as possible on the servers themselves so if it makes sense I’d prefer not to run a firewall on the machines that run the VM’s, unless running a firewall on Proxmox uses little resources.
Any recommendations for a hardware firewall in case I’d need one? I’ll have a /28 subnet, 1gbit drop.
Extra question: can anyone point me in the right direction how to learn how to automate setting up a VM from a web interface (user can select an image/template, vm gets created and assigned one of the available IP addresses etc)
