Hallo zusammen, ich bin gerade dabei mein Netzwerk von Fritz Box auf ubiquiti umzustellen. Mein Proxmox Server läuft aktuell noch direkt über die FritBox (192.168.178.X). Ich möchte aber den Proxmox Server in das Netz von ubiquiti (192.168.1.X) umziehen. Wie kann ich dies am einfachsten...

Hello, I have used proxmox before however this time on my new device. dell optiplex 3040m I have removed the WiFi card. When I log into root and try command /etc/network/interfaces I get told Permission denied, even though I am logged in under root. cat /etc/network/interfaces ip a Not...

In the Proxmox Virtual Environment (PVE) 8 system, after the physical machine was unexpectedly powered off and restarted, the business address could not be connected. One could only access the background through IPMI to check. In the system network, the network card was in the “up” state, the...

Hello Proxmox Community, I'm encountering a persistent issue with my Proxmox VE 8.3.0 installation where my Linux bridge vmbr0 is not correctly recognized by the Proxmox VE web UI, despite being functional at the OS/kernel level. This problem has existed since the initial installation of the...

I have a very peculiar issue which I never saw before, and which took me forever to even narrow down to PVE host. My server has a single interface that carries multiple VLANs. Then VMs are attached to particular VLANs. My network config (here limited to two VLANs) is quite simple: auto ensfp0...

Hello, I faced a bit strange behavior for proxmox UI dashboard, related to graph "Network traffic". The graph just empty. Screenshot attached: pve version 8.2.0 I'm thinking that it might be because of our network setup. Here is what we have across all hosts: $cat /etc/network/interface auto...

您好，先生、女士。 这个问题大概是4月29号左右开始出现的，当时我在Proxmox虚拟机上打开Chrome访问网站，就报连接超时。昨天同一时间还能连接。 随后，我开始了一系列网络故障排除操作，包括重新配置全局网络配置、重新初始化 DHCP 服务器（PVE 虚拟机使用 DHCPv4，IPv6 是手动设置的）。然而，连接超时仍然清晰地显示在我面前。...

We have a single Proxmox host running 8.4.1 connected to a Juniper 4400xd-48F switch. The object is to use two SFP+ connections on the Proxmox host to connect to the Juniper switch which will also be networked to our primary storage unit for NFS VM storage. If we connect to the switch via a...

Hey there, I am in the process of migrating my entire cluster, consisting of three nodes, to a new subnet. Old addresses: 10.10.20.11/24, 10.10.20.12/24, 10.10.20.13/24 New addresses: 10.10.0.10/24, 10.10.0.11/24, 10.10.0.12/24 I have already updated all necessary files, following a...

I am running a Proxmox Cluster in a nested Hyper-V environment. After the installation I login and create a Windows VM and assign "vmbr0" as the Network device. But inside the VM I am unable to get an IP address. The Proxmox is connected to the network and is able to access the...

I want to set up a trunk on my switch and create a bridge in Proxmox that I can assign to a VM. Within the VM, I want to be able to treat the interface as though it is directly connected to the switch, with the trunk available. Then I want to be able to create sub interfaces on the VM on...

1.I find that I can capture the IPV6 Neighbor solicitation packet on my virtual machine but on the pve vmbr1 I can not caputre the packet.. My topology is vmbr1 is the linux bridge of enp2s0, and my virtual machine's eth1 is bridge the vmbr1.. please see the attachment of the capture...

I recently needed to change the IP structure of my proxmox cluster. I broke the cluster and changed IPs. I have one system that has lost the vmbr0 interface which has completely caused the system to loose network access. I currently only have IPMI access. Here is info on the system: Proxmox...

Hi everyone, I’m trying to install Proxmox VE 8.4 on a machine with an ASUS PRIME X870-P motherboard, which has a Realtek 2.5Gb Ethernet adapter onboard. Unfortunately, during installation, I get a “No network interface found” error. The LAN port lights up, so the hardware is active, but...

Hey All, I updated from 8.3 > 8.4. Since this update and reboot... my Tailscale VM that routed two networks has stopped routing. Everything looks fine but I just cant get to any IP in the network that TailScale is routing. I have added the IP forwarding rules to sysctl and use the below line...

Hello! So we're planning to migrate our vCenter cluster over to Proxmox, and right now we've got a test cluster setup using hardware that's pretty close to what we intend to order. We'd like to use SDN on our new Proxmox cluster, and based on everything I've read in the docs for Proxmox...

Long story very short: I wanted disable IPv6 inside LXC containers and wrote this script based on information from links below: This script allows to disable IPv6 inside LXC container on Proxmox server. https://github.com/geoai777/proxmox_ipv6 Now here where I'm still fuzzy: ip a | grep...

I'm using a Hetzner Server with Proxmox installed. Currently I've got one additional IP-Adress, with seperate MAC. Using the following proxmox host interfaces config, i was able to assign that additional IP Adress to a VM, running pfSense ,while keeping the primary ip assigned to the proxmox...

Hi, I'm trying to install my first Proxmox VE. I assigned a static IP in the installation process (192.168.4.40). I'm using a Unifi Dreammachine as Gateway, the default network is 192.168.1.x . I created a new network without a DHCP server and assigned VLAN-ID 4 to it in my Unifi controller on...

I installed Proxmox over Debian 12 so I could keep my Windows partition on the machine I'm running the server on. After I installed Proxmox my ethernet did not appear to work on the machine (only wifi worked, which is what I used when installing Proxmox over Debian 12, not sure if that has any...
