I have run into a situation when creating VMs using the qm config command from the command line. The QM CONFIG command fails when I include any "net" options to create the VM NICs as part of VM creation. However, once the VM has been created, the QM SET command does work successfully with the...

Hi All, I have an Intel x540-T2 10gbe ethernet card that works perfectly with Proxmox 7.1-10. That is, until I try to create a Linux Bridge with it. The interface (enp139s0f1) works at the pve host level as one would expect... ssh, nfs, etc. all work. If I take that interface down and create...

We are solving a long term issue with a 3 node proxmox CEPH cluster. From time to time one of the nodes in the cluster just accidentally reboots. The physical setup is as seen here: Lets focus at pve1 configuration which represents the same config at the other nodes. Here is the pveversion...

Hello all, I am very new to the PVE world, and I am trying to test the SDN beta feature. During initial configuration I am running into an issue that is not posted anywhere. I have installed the libpve-network-perl & ifupdown2 packages, everything seems to go smoothly when creating controllers...

Hey Everyone, I am slowly reaching the end of my Ceph Cluster project and the absolute last thing I need to accomplish is setting up my PVE so that I can create VM's for the different VLAN's in my existing environment. So far I can confirm I can create VM's and have them migrate successfully...

I've been starting to expand my home lab a bit, and I installed proxmox 7.1-7 on a thinkcenter. To test things out I created a Windows server 2019 vm, an Ubuntu 21.04 server vm and an Ubuntu 21.04 LXC. Some details about the network: - Gateway is at 10.10.15.254/24 - Proxmox is at...

I am curious if there is away to do this without expensive hardware. .. What I am looking to do is separate one particular VM from my Host/VM ip scope. My host and VMs currently using 192.168.0.0/24 but I have a linux vm that is accessible from the outside via SSH and would like to separate it...

My hosting provider is Vultr; I run Proxmox on a dedicated BM server. The host perfectly connects to the internet; however, any VM I create does not connect to the network. Desired outcome: The hypervisor Proxmox has its public IP, then one VM should have its dedicated public IP (the second...

I have a Ark server setup and running in a Windows server VM on my Proxmox machine. I can connect to my server in Ark when I am home and on my local network, but as soon as I try to connect when I'm off my home network I cant join. I've setup the firewall in windows to allow the ports, and...

Hello, I am having a very odd issue with my setup - it is on PVE (7.1-10) running on a Hetzner dedicated box and using vSwitch additional network. Background and setup: I have a Hetzner vSwitch attached to my server. That vSwitch has an additional /28 public network on it. When working with...

Recently hired, I don't think this is a perfect proxmox setup and would like to improve it. Currently, our proxmox cluster has its 3 nodes assigned public IP addresses that we use to connect to them. Fairly randomly, we lose http connection to a node(s) and then just connect to one of the...

Servus zusammen, ich habe bei meinen VM's ein Problem mit der stabilität im ausgehenden Netzwerk Traffic. Solange nur ein VM aktiv ist hält sich der Traffic stabil, in dem Moment in dem aber auf dem Host System gearbeitet wird oder eine zweite VM zugeschaltet wird, bricht der Traffic alle paar...

Hello, I recently updated my Proxmox VE 6 server which led to all my VM losing access to the internet via a bridge made. I googled some fixes and found one which looked promising, it included entering the public IP in I believe the CIDR field of vmbr0; upon doing this it did not fix my issue...

Hello, ProxMox community, The problem I have recently purchased a Converged Network Adapter (NIC) Intel 82576, and I am having problems setting this up. When I start up Proxmox, the computer isn't connecting to the internet. When I am in the BIOS, the NIC lights up as it's receiving data but...

Hallo zusammen, und erstmal Frohes Neues! Ich versuche aktuell auf meinem Server Nat mit einer Zweiten IP einzurichten. Der Server verfügt über eine "Hardware" Netzwerkkarte. Ich würde gerne die IP des Hosts, und die Zusatz IP worüber das NAT funktionieren soll trennen, so das die Container...

Mainly, it would be fantastic if someone could give me a "here be dragons" on using Proxmox SDN with policy-based routing (i.e. multiple gateways with iproute2 tables + `ip rule`). I would like some more advanced networking (e.g. multiple NICs: i have will have 4 very soon). In configuring...

Hi, I am a little bit of a beginner when it comes to the IPv6 protocol and the way Proxmox/linux handles it. For context, we run a mail server on a guest inside a Proxmox box (bare-metal at a web farm). Everything IPv4 is configured and works great. Recently however, a client's MS Exchange box...

I would like to make a router for a 10G+ bandwidth (BGP+QoS+Firewall). Of course I will passthrough the network cards inside to the VM/Container. What is better for that purpose: Container or Virtual machine?

Hello, I can not resolve any hostname on my debian vm as long as ufw is enabled on proxmox. is there some configuration or some rule that I can add? I'm running proxmox on a dedicated server, the installation was made with the hoster's iso. it originally came with following networking: auto...

Greetings, We're running ProxMox 7.1-5 on Dell R7525 servers (AMD cpu) with (2) Dell Broadcom 57414 Dual Port 25GbE SFP+ nic cards attached. We've got (2) 25GbE switches cabled correctly and connected to our ISCSI storage appliance. One card is in Riser 1 and the other is in Riser 3; I'll...
