sdn

I have pfSense in front of my Proxmox cluster and I’m trying to configure SDN using VLAN 60 for a LXC container. • Zone: untrust (bridge: vmbr0) • VNet: VLAN tag 60 • Container: LXC set to use bridge untrust, gets IP via DHCP (in correct 10.10.60.x range) The container gets...

We're evaluating Proxmox SDN for our multi-site setup and running into some design limitations. We have several divisions, each spanning multiple physical sites. Each site assigns its own VLAN ID and subnet per division. Site-to-site connectivity is handled via IPsec tunnels at the router...

I have a currently 4-node proxmox cluster (more coming soon), and I have on each node a bridge connected to a bond for two adapters dedicated for my VM's to talk to each other. I need to create about 100 vlans, and with the migrations from my old vmware stacks, I may add up to 300 vlans. My...

I have been trying to get this to work for about a year now with no success. I have a three PVE cluster with three nodes. all PVE 8.4.1. I have two VMs, on different nodes but the same cluster. I need to have the two VMs to communicate with each other using static IPs over a private network. I...

I'm trying to setup a isolated VLAN network with SNAT so containers and vm's can reach out to the internet. Using SDN I: Set up a VLAN zone connected to vmbr0 Created a vnet connected to the zone with tag 100 Created a subnet connected to the vnet with subnet 10.10.10.0/24 and enabled SNAT...

Hello folks, well... I know there are many other posts about this and I'm just not sure if I did everything that was suggested in those posts but so far: 1. used multiqueue in both VM adapters 2. tested in the same node ~13gbps throughput (iperf3), and different node ~1.6gbps with or without...

I'm new to Proxmox and I'm trying to create a 3 node cluster with an isolated network. This way if someone hacks into a VM or Container they don't have access to my full network. I might also want to group and isolate some containers from each other. For example home related containers and...

Hey! How are you people? I was testing SDN fault tolerance and after a while struggling to make everything work as I intended, finally it's alive. But thing is that after testing a "node purposefully takedown" to try HA and see how much time it takes to reboot a vm and all of that, the node I've...

Hello! So we're planning to migrate our vCenter cluster over to Proxmox, and right now we've got a test cluster setup using hardware that's pretty close to what we intend to order. We'd like to use SDN on our new Proxmox cluster, and based on everything I've read in the docs for Proxmox...

I am having trouble configuring a VLAN VNet for my virtual machines using Proxmox SDN. After adding a zone and vnet I get the following error on some hosts: "error vmbr0" For example, the VMNet has the error on this host: But it succeeds on this host: All my hosts have the referenced vmbr0...

I have a pve 8 standalone node that came with the regular vmbr0 and vmbr1 bridges. When creating VMs and attaching them to these bridges everything works perfectly. I decided to use Proxmox SDN to have better native control over my subnet configuration. For this, I have done as the docs said...

Hi, The SDN section in the "Datacenter" item from the GUI's left-hand list disappeared (it is visible very briefly when the page load, but disappears in a fraction of a second. I cannot create any software-defined network anymore. When trying to create one using command-line, I get...

Hello everybody, I have been using Proxmox for several years now, and I have recently been offered the opportunity to setup a 4-nodes cluster as a way to test things out. My setup is the following, I have 4 nodes each one of them have the following network configuration: - 1x Gbit NIC used in a...

Hey, Perhaps I'm looking for something that doesn't exist or perhaps its just one checkbox away, all help is welcome ! I setup a 2 node cluster, and i setup a simple zone with ipam (pve). vnet0 gives out ip's 10.0.0.0/24. To all vm's and lxc that have vnet0. This works perfectly. When I...

I have a user on my cluster that I want to give permission to edit their own vnet firewall rules. I created a separate SDN zone for them as I don’t see a way to give permissions on just a single vnet. I can give them permission to use that SDN zone, but I can’t find a way to give them access to...

Going through the Software-Defined Network guide, and the Setup Simple Zone With SNAT and DHCP I couldn't find much details on configuring DNS host names, just some tips on linking the system to PowerDNS. I came across this youtube guide using Local DNS with Dnsmasq running in Ubuntu LXC which...

Hello, On the configuration generated by Proxmox SDN, this one select as router-id/IP in route-map correct_src the only IPv4 available during installation. Since then, I've added a loopback for redundancy, and would like use this for router-id/correct_src. Because even if this loopback is...

Hello, I try to setup a IPv6 plage into my EVPN zone (shared into 3 PVE in my cluster). I configure the IPv6 subet on the Vnet and it's working. I can ping the gateway from VM/LXC with this Vnet associted. My 3 PVEs are exit-node and share prefixes with my network via a BGP controller (to...

I want to use SDN's DHCP to assign IP addresses to the virtual machine's tap device, but I find the dnsmasq config file which managed by PVE itself has this optiondhcp-ignore=tag:!know. So if the MAC address is not in the list of addresses assigned by PVE, the DHCP server can only receive the...

Hello, I'm trying to migrate from vlan to vxlan, and I'm trying to figure out how to best bridge between a vxlan and a vlan. My initial thought was to use a linux vm and just bridge between two interfaces. While this will work, I'm wondering if there is a better way to do this? I know that it's...
