I have a cluster with 3 nodes. All in all, this works perfectly. However, if I want to copy a VM or ISO from one of the first two nodes to the last node, the copy process aborts after about 1GB and the third node appears as offline. However, when I click on it, everything is displayed and...

Hello everyone! Please tell me what the problem could be? There is a server with a PCI-E card with 2 SFP ports 10/25 GBs installed. There are 2 Qtech switches in the stack, each of which connects the server to AggregatePort. The ports are configured in trunk. Vlan for hypervisor management is...

Starting today, any new LXC containers I make have terrible network performance. Any downloads I make start out full speed, and then over the next 30 seconds they peter out to nothing and eventually time out. Example download on the PVE host: root@nuc13:~# wget...

I've got 2 servers in a Proxmox cluster and each of them has a nic which has 4 10g sfp+ ports. I've taken a transceiver and connected it to a fibre cable to a USW Enterprise 48 PoE switch. This was working fine until a while back were both servers lost connection over fibre. I ran an ethernet...

Installed a PCIx4 Intel Chip WiFi card after initial Proxmox setup. Cannot see WiFi card under network devices in Proxmox, but can do raw PCI Pass Thru to VM. With PCI Pass Through to Linux VM (OpnSense FreeBSD), WiFi card is detected and driver is loaded, dmesg below. But the device does not...

I want to assign a public IP to each VM in my proxmox server, I have made a bridge with my /24 subnet mask. I have VMs with Ubuntu server OS, I know that I can assign IP by Ubuntu server, but I want a method that makes one IP only can be chosen because I'm going to start renting VPS company.

So i just installed a new interface which i had laying around (it was really cheap). And my goal is to use that INterface in a other Network. But i doesnt show up in the webgui and int the interface file it also doesnt show up. Is the Interface maybe incompatible with Proxmox or are some...

I know I am crazy here to configure this kind of networking but I want to try if possible. Also a noob about networking. My PVE host have two physical interface, ethernet enp5s0 & wifi wlp6s0. Both connected to different network. enp5s0 is connected to 192.168.1.0/24 network while wlp6s0 is...

Hello. I'm new to this. A few days ago, I installed Proxmox VE on my PC, and everything was running fine until last night when I discovered that the host machine could no longer access the internet. However, all virtual machines are functioning properly and can access the internet without any...

Hello, I have several servers rented from my provider—let's say three, for example. Each server has an external IP address that I only use for configuration purposes via SSH (125.10.10.*). All servers also have internal IPs, which I use for internal communication between the servers...

Hello, I would like to set up an environment with multiple VMs running on a single server and assign an individual static IP for each of the VMs. The main server would be connecting to a single router with a public static IP. Is there even a way to do this? I am new to this so apologies if this...

I try to replace my routers DHCP Server with the ISC Kea Server in a LXC. As I'm new to this, I want to try it on a few client LXCs first. For this I want to block all DHCP requests that would go to the router and all DHCP requests that could reach the new DHCP Server from the outside of the...

Hi, I've got a strange issue with the last kernel 6.8.12-1-pve and my network card Sun ATLS1QGE. The card is drived by the "niu" module. Proxmox is constantly reporting for each interface connected "link down", and few seconds later "link up". I've got a lot packet loss, sometimes it was...

Hello, I've been trying to achieve this setup for quite some time, but without success. What I want is to configure vmbr0 as a bridge, which will use MASQUERADE for all VMs within the 10.10.10.0/24 subnet. It's fine for me if these VMs use the main IP address. However, I need one specific VM...

For testing and experimenting, I installed Proxmox as a virtual machine on my TrueNAS server and noticed that I cannot ping or access anything on my TrueNAS host from the virtualized PVE. My TrueNAS IP: 10.0.1.10/24 Virtualized PVE: 10.0.1.203/24 My TrueNAS network setup is straightforward -...

I have a proxmox cluster with two nodes with SDN VXLAN configured. Connections between containers and VMs work very well, also from different nodes. Unfortunately, I fail to connect the nodes themselves to this VXLAN. Could someone please help?

I was looking for many other similar questions but could not find any exact answers. In my case I have three server's ha network on 65 subnets and they are connected to one another using 10GB wire and ports. 1 VM is running on each node and is part of a cluster. I tried to tune my pacemaker...

Hello, I'm running in yet another problem! I have a Windows 11 VM on proxmox, this is pure for downloading. Everytime i'm downloading and the download goes around 30 mbps I get the following messeages: After this I lose RDP connection for a few seconds and Unifi tells me the device is...

Hey, I need some help... In my home network (10.1.0.0/16), I have a Proxmox server with a WireGuard LXC container. From this container, a VPN tunnel (10.7.0.0/24) is established to my second Proxmox server in a network at a friend's place, where I don't have access to the router. Therefore, I...

Hey everyone! I'm having quite the wild issue. I've created an LXC for Wireguard, for which I have also added the needed lines in the config of the LXC in itself as well as on the host, as per the OpenVPN installation guide. However, it seems I can't connect to it; what's more, in contrast to...
