network configuration

I have Proxmox setup with a single network card and software bridge. The physical network the host is connected to provides IPv4 via DHCP and IPv6 via SLAAC. I can create VMs with VirtIO NICs and the firewall option disabled, install Linux and everything works (the VM gets IPv4 and IPv6...

Background: I am a relative networking novice and what I have learned has been mostly by accident and preceded the advent of useful AI's so is quite cobbled together. I have somehow managed to set up what I believe to be a relatively secure network and am trying to be prudent about how I add...

My ISP has assigned me a block of ipv6: 2001:19c0:1::1c00/120 I'm currently on Proxmox 7.4. After setting up a new Ubuntu 22 LXC, I've added network settings like so: Static IP: 2001:19c0:1::1c03/120 Gateway: 2001:19c0:1::1c01 I've also tried updating the bridge on the node to include an...

Good evening, I am interested in being able to connect two Proxmox servers to each other and that the VMs of both can be seen no matter where they are. The idea is that they work as if they were connected under the same switch, but the problem is that they are connected P2P. Both nodes are seen...

Hello! I have been trying to setup a server for a student radio at my school. This is my first time working with Proxmox. The reason I choose this software was becuse of the flexibility it creates but right now it's been more of a brick wall that I haven't been able to get past. The current...

I am new to Proxmox and I'm setting up my first server. So far the only thing I'm confused on is the networking. I currently have a linux bridge (vmbr0) and a linux bond (bond0). Do I need both or can I get away with just having the bond? My host has 4x 1gb nics and I want to bond all four of...

Moin Moin und frohes Neues alle Zusammen! In meiner Proxmox Installation habe ich folgendes Problem: Die Hauptnetzwerkkarte wird nicht richtig erkannt. Früher war es tatsächlichg mal eth0. Jetzt nach zwei neuinstallationen irgendwie nur noch lan0. Auch der Typ wird nicht angezeigt UND im GUI...

Hello, I do have 3 identical Hetzner servers that I configured with their Installimage script - Hetzner-Installimage - and configured Network Bridged setup accordingly to their documentation - Hetzner-Proxmox-Network - configuration of network is similar on each host. Hosts are fresh, no VMs...

Hi, I'm fairly new to Proxmox VE, and been wanting to use Tailscale for external access to my home services. I currently have VLANs setup on my network, which is working fine. I wanted to put Tailscale on a new Proxmox VM that is under a VLAN seperate from the rest of the other VMs. I wanted to...

I currently have two proxmox Metals in Scaleway Cloud. Yesterday I bought my second one but with the first one I didn't have any issue. So my setup in the first one is a pfsense firewall with a WAN and a LAN in 192.168.1.0/24. Now I introduced the second Metal and created another pfsense (I know...

I'd like to Pre-generate the Mac Address for a tool I'm building. I'm currently using one for VMware (and VMware only allows specific MAC addresses) and wondering if Proxmox has something similar? Is there a Proxmox SPECIFIC Mac address generator? (i'm guessing there is a function in the...

When I installed proxmox, I installed a 4 port network card for a pfsense virtual machine. i scrapped that and debridged the network card connections but when i remove the network card, proxmox won't connect to the network. The ethernet is connected to the motherboard. I have VM's set up and...

Hello everyone. I have a somewhat unconventional task and could use some help as networking isn't my forte: There are two networks, each with public IP addresses: Subnet Address: 52.102.119.228/28 Default Gateway: 52.102.119.229 and Subnet Address: 11.286.202.192/28 Default Gateway...

How to correctly configure vlans on a Proxmox Backup Server? When I try to create a Linux Bridge with the name "vmbr0.99", the name field border gets red and the tooltip "Format: vmbrN, where 0 <= N <= 9999" appears. Possibly similar to: https://forum.proxmox.com/threads/vlans-in-der-gui.125579/
