Additions
Storage
When I ordered my server with Hetzner, I only loaded two NVMe SSDs into it. As I grew into my server and needed more storage, I contacted their support to add additional drives. Details and prices for the drives can be viewed at this link, and whatever the server configurator allows for an upgrade is possible to add at a later point.
When the first additional drive was added into my server, I was able to set it up from within Proxmox:
Click on the Proxmox node → Disks → new drive that’s been added → Initialize Disk with GPT
Afterwards, click on Disks → LVM → Create Volume Group
You should be able to select your freshly initialized disk, name it what you want, and then enable Add Storage and click on Create.
Afterwards, click on Disks → Directory → Create: Directory.
You should be able to select your freshly initialized disk, select ext4 (or xfs if you prefer), name it what you want, enable Add Storage, and then click on Create. The name that you choose will then be a part of the path to this directory:
/mnt/pve/NAME-GOES-HERE

Thanks, John!
Great post. Thank you so much – exactly what I was looking for!
But I’m missing a step-by-step guide to include Traefik 2 to your setup.
Or can’t I simply find it?
Hi Fred,
I try to split complex topics into their own articles. You can find my Traefik 2 guide at https://LTG.FYI/Traefik-2. Please let me know if you have further questions, and I’ll try to answer them here or perhaps write additional articles.
Best regards,
Louis
Great post. Thanks!
I’m just in the process to replicate your setup.
Nearly everything is working but I can’t get any DNS servers working on OPT2. The traffic is routed over the WireGuard-VPN, all fine.
But it seems that any UDP traffic is blocked and I can’t figure out where to unblock it. Any hints much appreciated! Thank you.
Hi Andreas,
Off the top of my head, maybe I forgot to document the DNS Resolver section, but will have to go re-read my article and look for anything that I might have missed, but am in the middle of bee season (video of some of it: https://LTG.FYI/YouTube) and helping restore multiple ranches, so it may take me a moment.
I’ll e-mail you and try to figure it out with you. Once you and I figure this out, I’ll make appropriate edits to the article or one of us can write here in the comments about what needed to be changed.
Thanks,
Louis

Thank you so much for your tutorial!!!
I can’t access the Ingress server from the VMS_Hetzner network, from external it’s working.
Like in your example: “Now I can access the simple server remotely by visiting http://65.109.71.115:8000”
I can access the website from my browser, but not from a browser running with any VM on the VMS_Hetzner network.
Any idea which Firewall rule is blocking the access from VMS_Hetzner to WAN_Hetzner?
Hi Loomer, you are most welcome! 🙂
I used the interface’s address for the VMs to access the firewall interface. Please see https://thad.getterman.org/articles/proxmox-7-behind-firewall-vm/5/#live_desktop for an example of a Virtual Machine accessing the firewall’s GUI via the VM interface address to configure it instead of the WAN address.
Best regards,
Louis

I am new to proxmox and your article just blew me away.
I just got the hetzner with 15hdd (no nvme) and I asked for KVM to install proxmox directly on the baremetal
But you do some sort of magic.
you boot into recovery and install proxmox in qemu?
I cannot say I follow
I am not sure I follow (and obviously I already broke my setup trying to change the network settings)
Hi Marcin,
I’ll e-mail you so that we can schedule a time for me to have office hours with you; you screen share with me in observation mode so that I can tell you what to click on and help you get up and running.
I’ll make a YouTube video out of it and then add one or more relevant videos to this article.
Talk soon,

Hi,
Thank you very much for sharing this tutorial. It was extremely useful.
My home lab server was running for a few weeks without any problems. However, I have decided to upgrade Proxmox from v7 to v8 this week. I temporarily updated the /etc/network/interfaces file with the configuration in the /etc/network/config-recovery file. The upgrading process ran smoothly, and, in the end, I have updated the /etc/network/interfaces to the original configuration. Everything is working except the fact that in the Proxmox instance, I have no access to the internet. After some debugging, I noticed that, with the upgrade, the default gateway of Promox changed to 172.16.0.1. The output of ip route show is:
default via 172.16.0.1 dev vmbr2 proto kernel onlink
172.16.0.0/24 dev vmbr2 proto kernel scope link src 172.16.0.0
192.168.1.0/24 dev vmbr1 proto kernel scope link src 192.168.1.2
If I delete that and manually define the default gateway to 192.168.1.1 everything works normally. Also, if I comment the line with ‘gateway 172.16.0.1’ in the /etc/network/interfaces, the problem is solved after restarting the networking service. I am not sure if I am supposed to do that, as you had that line in the /etc/networks/config-runtime file
