# Proxmox Setup with 1 Public IP ## Requirements * A dedicated server (you can get it from [Fiberstate](https://billing.fiberstate.com/aff.php?aff=185)), some others may work but may need additional tweaks to hardware identifiers * A SSH Client (we used [MobaXterm](https://mobaxterm.mobatek.net) but you can use PuTTY or OpenSSH or the built in SSH client) ## Server Preparation We recommend to get this server spec (R9 7950X)

Input your desired Hostname and Password, and for the Operating System choose Proxmox (latest)

{% hint style="success" %} They have double drive promo on going, drop your invoice number to their [forum thread here](https://lowendtalk.com/discussion/200196/b-l-a-c-k-o-u-t-f-r-i-d-a-y-fiberstate-mega-event-new-la2-dc-giveaways-kaboom#latest) {% endhint %} Go to your web browser and access your proxmox web console by accessing this URL https\://\:8006 and use root as username and the password you set previously

{% hint style="info" %} Additionally, you can run this script for post installation setup for basic proxmox tweak {% code overflow="wrap" %} ```sh bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVE/raw/main/misc/post-pve-install.sh)" ``` {% endcode %} {% endhint %} ### Prepare SDN function Login to your server via SSH and run this command ```sh apt update apt -y install dnsmasq # disable default instance systemctl disable --now dnsmasq ``` Make sure you have this line in your /etc/network/interfaces file ```sh source /etc/network/interfaces.d/* ``` type the following command to check ```sh cat /etc/network/interfaces ``` If source /etc/network/interfaces.d/\* is present, proceed; if not, add it to the file by using this command ```sh printf "\n\nsource /etc/network/interfaces.d/*" >> /etc/network/interfaces ``` ### Creating SDN Network (Private IP) Go to your Proxmox web console and go to Datacenter > SDN > Zones > Add > Simple

Tick the Advanced option, put ID with any name you like (in this case we use cnid) and tick the automatic DHCP

Go to SDN > VNets and Create

Input the any name (in this case vnet1) and select the zone that you created previously (in this case cnid)

Click on the newly created vnet and on the right side, click create

Input your own Subnet and Gateway, you can customize it or just follow, and then go to DHCP Ranges

Click Add and input your desired IP range (in this case 10.100.0.100 - 10.100.0.200 ; more than enough) then Create

After this setup, go to SDN and click Apply

After that go to IPAM and you can manage your DHCP reservation (this image taken from my running server)

### Download OS Image Go to local storage > ISO Images > Download from URL

We will download ubuntu 24.04 iso for later VM setup Input this `https://releases.ubuntu.com/24.04.2/ubuntu-24.04.2-live-server-amd64.iso` to URL field and click on Query URL you can rename the file if you wish and click Download

{% hint style="success" %} Now you've done the server preparation, we will continue to VM Setup {% endhint %} ## VM Setup Simply click on Create VM button on top right of your interface ### General Tick on Advanced box > tick on Start at boot > put the server name > Next

### OS Select local storage > choose the ISO Image that you downloaded in previous step > Next

### System Just next, nothing to change there ### Disks Select local-lvm in the Storage section > put 100 for Disk size > Next

### CPU Set Sockets and Cores depends to your need and Type to host for the best performance > Next

### Memory Set the Memory depends on your need > Next

### Network Select the bridge that you created previously > Next

### Confirm In the confirmation page, you will see the summary of the VM. Optionally, you can tick Start after created so it will start immediately > Finish

### OS Installation After VM Creation, go to Datacenter > your server name > Console
