## Overview of Proxmox SDN Setup
– **Introduction to SDN in Proxmox**: The video begins by introducing the concept of Software Defined Networks (SDN) in Proxmox, elaborating on its novelty and potential use cases. The presenter mentions the previous videos where Proxmox was installed and container templates were set up.
– **Preparatory Steps**: Before delving into SDN setup, the presenter underscores the importance of checking system prerequisites through specific commands, ensuring that the system is equipped for SDN implementation. This ensures that viewers are ready to proceed without hiccups during configuration.
## Configuring the SDN
– **Installing Necessary Packages**: The video presents a step-by-step guide on updating the system and installing packages like DNS mask and Frr for routing. The process involves executing commands to disable the default instance of DNS mask and install other essential components to aid in SDN functionality.
– **Creating and Applying SDN Components**: Detailed instructions are shared on creating the SDN, including setting up zones, vnets, and configuring DHCP settings within the Proxmox environment. The tutorial ensures that even action as complicated as networking is made approachable through systematic guidance.
## Finalizing and Testing the SDN Setup
– **Launching and Connecting to the SDN**: Once the SDN setup is complete, the video shows how to clone a container template and attach it to the newly created SDN. This includes adjusting network settings and ensuring the correct bridge is selected.
– **Verification and Conclusion**: The final part involves testing the network connectivity to the internet and verifying the correct subnet and IP address assignments. The video concludes with thoughts on potential use cases for SDN in Proxmox and encourages viewer interaction through comments and a blog post.
This structured breakdown ensures viewers can easily follow the complex process of SDN setup in Proxmox from preparation to full implementation and testing.

Respect your work, but this felt kind of like you made it just to have content. Not meant negatively, but as you said you don't have a use case for it. Without more background of what/why etc, how do we know if we would benefit from setting it up or not?
Very nice thanks for sharing man. I'm sharing some services with people outside my network using tailscale serve and funnel and this would allow me for those services to not be on my main network. Nice.
What can this be used for? Could you make a video maybe explaining the different usecases of sdn on proxmox?
Wooohooo! Made it!
awesome ty!
I need to know how to install proxmox in a server which is remote and the steps needed and also need to install in almalinux 8 or rocky linux 8
I think the only way I would use SDN (with VPN setting if that's possible) would be maybe for the container sets for downloading wink wink.
@9:49 – can you add multiple DHCP range per subnet ???
because it looks like you can click the "Add" button again.
@8:35 – can we create IPv6 subnet ???
SDN has always interested me and I want to have a use case for it as well. I see this as being key to have a mini router that is very basic for connecting VMs and CTs to the internet but wonder if it separates them from the physical network enough for security without involving the firewall rules. That is the other thing I want to work on is actually using the proxmox firewall.
i've not looked into SDNs yet but it looks nice, i make use of SR-IOV so i give each container / VM their own dedicated nic but one of the features of esxi which i used before migrating to proxmox, was a private vlan which essentially was a /32 isolated network
i wonder if you can do similarly with the SDNs in proxmox
Thanks for sharing DB Tech.
Really Enjoying this series on Proxmox. Great Job!
Just in time! Now I can segment my containers and VMs into the desired range of IP addresses. Currently, I share the internet with a flatmate, and since we both work remotely, I'm concerned about disrupting our internet access. However, with Software Defined Networking (SDNs), I can continue to experiment and organize my VMs and containers without issues. Thanks for your video; I'm definitely going to give this a try!
Great video sir! Thanks
Hi! I'm watching all the series about proxmox (as I watched all you past videos) because I'm planning to switch to it soon. Actually I'm using a RPi4 with OMV6, docker and portainer/dockge, one of the container is gluetun and there are a couple of other containers "linked" to it. I was wondering if I wanna create separate nodes as you do how can I communicate with gluetun and the other nodes, I don't know if you understand the question. I think you only talked about gluetun creating different "containers" in the same node where gluetun was installed. Thank you for you help
Interesting how fast vms can talk with each other when using sdn. Will it work faster than device physical nic speed…
Great explanation! thanks
Il livello di rispetto reciproco in questo thread è davvero incoraggiante. È un brillante esempio di come dovrebbe essere condotto il discorso civile.🍭
Hello David keep it going. I like your videos, I follow you since years ago. Keep it going awesome 👏🏼
