ipv4

Hi everyone, I'm planning to set up MAC filtering for IPv4 traffic in my Proxmox live cluster and aim to use ebtables and ipset where necessary, but I would like to primarily rely on Proxmox's built-in GUI features for easier management. As I'm still learning Proxmox's firewall system and...

I am having a problem where after an update, I lost all IPv4 connectivity. IPv6 thought works This is my setup: 1. Running proxmox on a mini PC (Virtual Environment 8.1.11) 2. Network layout Pfsense (router) --> Unifi Switch --> Proxmox MiniPC (172.25.90.50) 3. Proxmox server is on its...

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.

I have installed pimox (proxmox in raspberry pi) and although it was running fine for months, i had to reinstall everything because disk corruption. Now, reinstalled pimox and installed a debian VM and Home Assistant VM.. Both are working fine with ipv6..but ipv4 is not working. They dont take...

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...
