I've setup a simple zone with automatic DHCP, a vnet and 10.0.0.0/24 subnet with SNAT enabled. On the host I have 2 bridges configured: - vmbr0 with public IP 1.1.1.1 - vmbr1 with public IP 1.1.1.2 (Those aren't the real IP addresses, just substituted by me). When creating the subnet and...

Looking to understand how can I get QinQ working with an OVS bridge. My topology looks like this: VM (will send tagged and untagged packets) --> TAP itf (configured with outer tag on proxomox UI) --> OVS bridge --> physical NIC --> C9300 Switch (which is configured to act in dot1q-tunnel mode)...

Tried posting back in March, but didn't get any responses, thought I might simplify things. I have an OPNsense firewall running as a VM under Proxmox. I have other VMs and containers also running under Proxmox. I have physical VLAN capable switches and network access points. I'd like to trunk...

We have been using a mixture of traditional Linux bridges as well as OpenVSwitch. Looking at the roadmap, I can understand a desire for stability but OpenVswitch is now well established, it's even available in the GUI now (and usable once apt install openvswitch-switch). It's also "under the...

Hi, I've just upgraded to 8.2 and after a little trouble with networking (interface names changed) I'm up and running and testing out SDN. I'd like to create an isolated subnet 192.168.100.0/24 that uses a specific upstream so that only machines within this subnet can talk to eachother...

Hi, As visible below, when setting SNAT for a simple network type: iface cu1vn address 10.1.1.1/24 post-up iptables -t nat -A POSTROUTING -s '10.1.1.0/24' -o enp43s0.709 -j SNAT --to-source PUBLIC_IP post-down iptables -t nat -D POSTROUTING -s '10.1.1.0/24' -o...

I've been playing around with SDN with a goal to implement a form of microsegmentation and believe that what I'm after is not currently possible without some form of work around. (VMs with multiple NICs etc) Is someone able to let me know if there is plans for the following on the horizon or if...

Dear Proxmox Community, I have an existing /27 Subnet on the main Bridge vmbr0. I now would like to have each VM assigned only ONE public IPv4. It's important that I do this on the Hypervisor side, since the Root user of the server should not be able to just add the whole subnet to his VPS. Is...

Hi, I have installed two Proxmox nodes set up as a cluster. I also set up SND with 2 VNETs on a VXLAN zone. On each node I set up an OPNSense firewall with three network interfaces, two of them on different VNETs, and a third one directly on a Proxmox bridge interface not using SDN. When I...

I have firewall enabled on the datacenter level. When setting up simple sdn with DHCP. Created a new VM, but DHCP address is not getting assigned to guest. If i disable the firewall, I am able to get a DHCP address without issue. Im assuming i need to add a firewall rule to allow, just not...

At Geco-it, we use the SDS Linstor solution. To connect our hypervisors without investing in switches we use a full mesh network To use Linstor storage in VMs (container volumes), we need access to the Linstor satellite network. So we need a VM Storage bridge... To setup full mesh network...

I'm having an issue transitioning to the Proxmox VE Software-Defined Network (SDN). Current situation: enp6s0f0 is an untagged network connection vmbr100 is a Linux bridge with bridge port = enp6s0f0 VM998 has a network device attached to vmbr100 This configuration works great When I try to...

Hi all! I've been playing around with EVPN SDNs. I have SNAT enabled on some Vnets. After some ping tests on containers, 8.8.8.8 is unreachable only once enabling the datacenter firewall. All outbound traffic is accepted by default, not sure if EVPNs require inbound rules to the hosts in order...

Hello All, I've been working on separating my virtual machines and containers from my home network. I've successfully set up a simple SDN zone to serve as an isolated network, achieving my primary objective. Now, I aim to route all traffic from this SDN through a VPN tunnel to a cloud-hosted...

I'm trying to setup EVPN in Proxmox using SDN but I think I have a skill issue or something any tips would be appreciated. I've setup the controller, it starts fine and establishes the EVPN, BGP session with my router but when I add a vnet I get the following error error: vrfbr_foo: bridge port...

I have needs to have multiple IPs/networks on the hypervisors, typically on different VLANs (like backups, corosyncing, ceph,etc. etc.) Having used OVS before, it is/was a charm to do similar, as you just add an OVSIntPort with the VLAN and IPs, and you are done. As the SDN is using Linux...

PVE version: 8.2.2 Netbox Version: 4.0.1 Hello, As stated in the title, I'm having issues deploying VMs when they are assigned to an SDN zone that uses Netbox for IPAM. When testing, I'm able to create a zone, vnet, subnet, and dhcp pool just fine and deploy a VM when that zone is set to use...

Busy FAFOing with this in a totally meshed setup, and the use case is to have Ceph on that SDN created VxLan/EVPN vnets of it's own. Reason to NOT have it on the "public" network, but also to allow VMs (pointing fingers to K8s) that wants direct Ceph storage access on the access network, and in...

Hi, I'm trying to create a SDN network on my cluster. Unfortunatly, SDN not working. This is my configuration: On each node I have a vmbr5 with a network 192.168.20.238/24 node 1 and 192.168.20.239/24 on node two Configure like doc my interface on my servers debian. But when I try to ping...

I just created my first SDN on my (single) Proxmox Server. The goal was to have manage various networks connected as VLANs to the host in a future Cluster Setup. The VLAN already existed as a tagged Network on all Ports and has a working DHCP and DNS Server (physical Router). What I set up...
