network configuration

Good evening everyone! I have a production cluster with 5 nodes. All of the nodes have one network card with: A dedicated public IP address on eno1. A vmbr4001 bridge for the public subnet of the guests (LXC). A vmbr4002 bridge for the private subnet of the guests (LXC). A vmbr4003 bridge for...

Hello Forum I have searched the forum for an answer for about a month now, but I am unable to find one, or a similar solution to my problem. Recently I made the decision to migrate to Proxmox as hypervisor after using VMware since 2012. It goes very well. I’ve got an LXC container running and...

Hello. Is it possible to change Native vlan to something else than 1? If so, just globally, or is it possible to make it per VM?

Hello! New to Proxmox and forums (experienced in other HA hypervisors). I just setup a 2-node cluster and I've been having some networking issues. I have two interfaces (enp1s0f1 primary & enp1s0f0 backup) in an active-passive bond (bond0). I then setup vmbr0 on bond0 and vlan2 onto vmbr0...

Hello, I have a Proxmox VE Server at Hetzner that I need to use for KVM virtualization (I have a /26 subnet). I want to create templates that will be later on used to fully clone then VM provisioning with Cloud-init. My first question: I am creating a VM from an Ubuntu Cloud Image. Upon boot...

I've recently got my hands on a PowerEdge R620, so I installed Proxmox for my homelab setup. However, I cannot reach the web based VE from desktop. Troubleshooting steps I've tried: Used different browsers/cleared cookies/used a private window Flushed DNS, released/renewed IP, rebooted on...

Hello guys, Couldn't delete this post, so I corrected it in place. got a "little" issue with 1:1 Nat on pfsense/opnsense, feels like one little piece on the proxmox side is missing. I hope someone can point me into the right direction. From hetzner, I ordered a second public IP address, which...

I installed ifupdown2 with apt install ifupdown2 and it installed from debian repos instead of proxmox. now, network connectivity is lost, and my server cannot boot from HD. I just have access to rescue mode. I tried Code: apt update && apt dist-upgrade , but still server could not restart...

How may I use Microsoft Remote Desktop to connect to a Windows VM hosted on Proxmox VE? I have the Windows VM hosted on a Proxmox server. The network configuration, as far as I can tell, goes like this: WAN ----> WiFi Router/Switch ----> Switch to NIC #1 (enp0s25) on server ----> enp0s25 to...

Hi everyone, I've been doodling around with Proxmox for a couple of months and, sadly, I've recently lost the onboard Ethernet port on the PC I'm using as a server, the same I used for the initial configuration. I have handy a USB to Ethernet adapter which is being detected via lsusb but I...

Hello everyone I struggle a bit to configure my proxmox network. Basically, I need to create a network different to my physicall network where I can put vms that can communicate together like "host - network " in VMWare. Here is the scenario: Let say I have two vms: the first one(FortiGate)...

While I have solved the issue, I hope this is helpful to others who run into the same problem. Also, it would be great if someone could verify that this is a sensible approach. Recently, we would lose the network connection to our PVE servers on a semi-regular interval. Virtual machines on that...

Hallo Community, ich bin warscheinlich der erste mit den problemen. Ich habe schon stunden damit verbracht eine Lösung aber die haben immer damit geändet das ich mich nicht mehr mit meinem Server verbinden konnte weshalb ich den dann neu aufsetzen musste oder die ändern einfach nichts bewirken...

Hello everyone, I installed Proxmox on a MacPro 2013. Because logically no further hard disks fit into these and I didn't want to spend any more money on an external hard disk housing with Raid function. I took my Fujitsu Esprimo P7936 and plugged in all my hard drives and connected them to a...

TL;DR I can ping 1.1.1.1, but I cannot ping the router on the same network, nor access the GUI from another computer. I’ve changed NIC’s before, when I swapped motherboards, so I have solved this issue before, but I’m completely stumped with how my setup is currently broken. I know there is an...
