sdn

tl;dr: I want to pipe VLANs around my networks, both the physical and virtual sections, to separate things like IoT out. Some more detail: I have a network consisting of Proxmox VE containers and VMs (one being OPNsense firewall router), and physical network components such as UniFi switches...

Hello! For some reason i need to add server with three VMs to VXLAN created with proxmox SDN. I tried to create basic VXLAN with # ip -4 link add vxlan100 type vxlan \ id 100 \ dstport 4789 \ local SomeIP But in good case it's just dont work in bad case in result i get ARP storm...

Hi @spirit, thank you for the amazing SDN support in Proxmox! I'm trying to interoperate with an EBGP overlay/EBGP underlay configuration generated by Arista's "validated designs" (AVD) Ansible collection. I have some Proxmox hosts that'll act as L3 leaf nodes in this network, connected...

Hello everyone, I'm trying to setup this kind of setup (with more VM, but this is the simplified version) : 2 proxmox servers (px1 and px2) 1 pfsense firewall (fw1) on px1 2 virtual machines (vm11 and vm21) on px1 2 virtual machines (vm12 and vm22) on px2 My contraints are : I want vm11 and...

Hey, Where does the VLAN tagging of the Ethernet frames take place? When I set the VLAN tag on the VM, the VLAN tagging is performed on the VM's network interface. So outgoing packets from the VM receive the VLAN tag. But what if I use “Linux VLAN”? Or just use SDN? At what level is VLAN...

Hallo zusammen, ich arbeite mich aktuell mit den verschiedenen Optionen der SDN ein. Dabei ist mir aufgefallen, dass wenn ich SNAT anharke oder generell up und down-Regeln in den Interfaces hinzufüge diese mehrfach angelegt aber nie gelöscht werden. auto default0 iface default0...

Hallo zusammen, da ich aktuell eine Netzwerkumstrukturierung plane, würde ich gerne das DHCP Plugin für eine VLAN Zone verwenden. Gibt es einen abschätzbaren Zeitraum in welchem wir eine Implementation des DHCP Plugins für VLAN Zonen erwarten können? Danke im voraus :) VG

I have started to use SDN network and it's work with VMs. I have created a cluster and I've added a new node. In this node SDN network is pending "local sdn network configuration is not yet generated, please reload" and /etc/network/interfaces.d/ is empty. Do I need copy files manually? All...

Hello, we try to build a PVE Cluster with a EVPN VXLAN SDN. The configuration for the VM to VM Communication is working, also SNAT with the Subnet Gateway is working. Now we try to replace the subnet gateway with an external OPNsense, so that the OPNsense can provide all required network...

Hey there, I have this strange issue with the current Proxmox 8.1 SDN-module, where DHCP replies don't arrive at the destination VM. I assume following setup: I assume that this setup works as expected, in that it pushes VLAN 90 onto all packages in vnet22A9, and every packet entering...

On a root server with one NIC I set up Proxmox VE 8.1.4 with two SDN simple zones, so I have three bridges configured: vmbr0 connected to eno1 with public IP, dmznet with SNAT and subnet 192.168.100.0/24 for nginx reverse proxy. Third bridge is labnet 192.168.200.0/24 for the application...

Hi all, i just upgraded from 7.4 to 8.1 and was trying to experiment with SDN. If I add a Simple zone, i cant seem to turn on DHCP anywhere. I did install dnsmasq. It's like there is no dhcp plugin at all. What am I missing?

Hi all! I've discovered an issue with VXLAN and routing, and I'm not sure if it's because my setup is wrong/weird or if it's a bug (possibly in the kernel). My setup is: Three nodes in a cluster, each node has an /32 address on loopback lo: vmhost0 10.200.255.10/32, vmhost1 10.200.255.11/32...

Hello, we want to setup Simple SDN zones with IPv6 but can't find any documentation about how to configure SLAAC or DHCPv6 for a Simple SDN zone in the WebUI. Goal: Netcup-VPS with two public static IPv4 addresses and two public static IPv6/64 prefixes -> Headscale VPN -> Proxmox VE node ->...

Hi, I configured 2 Proxmox 8.1.3 servers in one cluster and configure SDN zones as VXLAN. 1. No option turn on DHCP 2. When SNAT checked on subnet, no snat rules /etc/pve/sdn/zones.cfg vxlan: vxlan peers 10.33.3.20,10.33.3.21 ipam pve mtu 1450 nodes pve1,pve...

Hi, I'm testing the new SDN feature with some servers that are going in DC soon, I only get DHCP working with the simple zone. I can recall that I read somewhere that it was only working with the simple zone, is that still true, and if so is there any idea when it will work with vxlan? like a...

Hi, I just want to know how do you guys manage the networking for big proxmox clusters ? In my case I need to have multiple external networks for my VMs. For that, I create a dedicated vlan on my network switches and then configure a linux vlan interface on top of my linux bond and then add a...

Hello PVE enthusiast, I am currently administering 4 Proxmox nodes and each one is siloed so there is no direct networking between nodes. the network setup on every node is the same (it's the basic bridged network that i saw in every PVE setup tutorial): These are the linux bridges that i have...

Hello, I have a problem that I'm using VLAN SDN zones and at almost every VNet it looks good. But one VNet has a problem with packet loss (ping between VMs at same VLAN at same / diferrent nodes). I have a stack with 4 nodes, connected via 2x 25Gbps LACP (DACs to nexus 9300 series). This is...
