    SDN / EVPN: Ping not always working between Virtual Machines

    We have multiple (9 now, 15 on their way) Proxmox hosts in our 2 datacenters. Each node has an eBGP connection to two switches (ptp subnet /31) for the underlay with an unique Private AS number (ie. SW015 AS 4200000102 -- PRXMX01 || AS 4200000103). In the SDN controller each host has EVPN...

    Proxmox SDN EVPN zone: Containers are reachable via ping but inaccessible on ports (SSH, HTTP)

    Hello, I have recently set up an SDN EVPN zone on my Proxmox VE 8.2 cluster. The configuration appears to be partially working as I can successfully ping all containers from my Proxmox hosts. Additionally, I can access services such as SSH from other containers within the SDN zone. However, I...

    Node won't get rid of old SDN zone et al

    I have five nodes in a cluster. I am using SDN. The only zone I have now is "proxnet." I can't seem to get one of the nodes to remove the VXLAN zone that has since been removed from all the other nodes. I suspect part of the problem is that one of the VNETs associated with that zone has a...

    How can I create an isolated internal network for only the VM's with internet access with an internal DHCP using the same IP as the router?

    Networking SDN Roadmap

    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...

    One IP per one VM

    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...
