Dear Proxmox Community, I have an existing /27 Subnet on the main Bridge vmbr0. I now would like to have each VM assigned only ONE public IPv4. It's important that I do this on the Hypervisor side, since the Root user of the server should not be able to just add the whole subnet to his VPS. Is...

General question: I have a /28 subnet and am planning (as i have not many servers and vms) to give each of my vms a subnet ip. I already got this working, to a point, where i had internet, but i had no firwall whatsoever. I already did this before and had a single IP with an OPNsense firewall...

Hello, I am new to Proxmox. I have some problems with obtaining IPv4 addresses from dhcp in my LXC containers. When I reboot my LXC containers, they won't receive an IPv4 address anymore. I am not sure if this is related, but it seems this started occurring after I ran the following commands on...

Hello! I'm quite aware that there may be a few threads that detail similar issues like the ones I am facing, however this seems to be slightly special, especially with OVH's strange networking. The following setup is given: Proxmox VE 8 Host on latest Version with all Updates installed. Said...

Hey I'm currently setting up a server with proxmox and the problem is : we couldn't buy any public ip for the CT. I tried what I could to try and make this work but I can't quite figure out what I should put in IPv4/CIDR.

Hi, I've scanned the forums and read hundreds of threads here and on other forums as well - but nothing seems to help. I'm running a Proxmox server and it's connected to an Unifi UDM with three networks: 10.0.0.0/24, 192.168.0.0/24 and 172.16.0.0/24. The VLANS are tagged with 192 and 172 (which...

Hi, I am installing Flatcar in a Proxmox VM. I have already several VMs working under the `vmbr0` bridge. I disabled the Firewall while defining the VM in Proxmox. Everything goes fine during the install from the Flatcar Production ISO image. But when I `ip a` , only IPV6 is available under the...

Hello guys I've been facing problems since always related with configuring all LXC's and VM's with ipv4 + ipv6 in OVH. There are 5+ posts in this forum related with that, but not even a completely working tutorial so the community users can finally configure they're machines in the correct way...

Hello everyone. All of a sudden I'm having trouble resolving LXC hostnames. I think it started after the proxmox update. Now, if I ping LXC by hostname, it resolves as ipv6, but it doesn't ping with the ipv4 flag (-4). If I disable ipv6 in LXC, LXC will usually ping over ipv4. What needs to be...

Good evening, I wanted to try to POST a lxc with the api proxmox and putting in the net0 that: "net0":"name=vmbr0,ip6=auto,gw6=2001:470:c8fb:ffff::,gw=10.0.0.1,ip=10.0.0.23/24,rate=100" But when it creates my lxc, I look in the network tab and I have this: It does not replace auto with ipv6...

Hi, I had a problem after upgrading one of my VMs to Debian 11 so I made a rollback followed by a VM restart. Now the VM has lost it's IPv4 address, only IPv6 is available: My Proxmox version in use is: 6.4-14 Any ideas how this could happen and how I can get back the IPv4 address?

Hello, I have rented a dedicated server. I have proxmox installed on it. Now I want to use pfSense as firewall and for internal routing of the other VMs. My goal is to: - An IPv4 for the host on which proxmox runs and is callable on the internet over it. - An IPv4 for the VM of pfSense, so...

A few days ago i buyed more Ipv4 Addresses and since then, all my LXC´s and with the old and the LXC´s/on Windoof VM are without Internet. I already checked my DNS Settngs, but i found no errors. If i try to ping 8.8.8.8 or any ipv6 adress/domain i get a respond. But with ipv4 not. I already...

Hello, for the last couple of days we try to switch our Proxmox installation from a Linux bridge to a routed setup with Proxmox. The Linux bridge worked just fine, but won't allow us to route IPv6 traffic to the VMs at the same time. Still we can't employ a IPv6 Linux bridge as Hetzner doesn't...

I have a working REST API Connection to proxmox. I can create and clone an LXC container just fine using the API. After cloning a container, I am trying to use the REST API to set the containers IP Address, but it's not working. My NodeJS code is below. let formBody = await...
