Hello. I'm new to this. A few days ago, I installed Proxmox VE on my PC, and everything was running fine until last night when I discovered that the host machine could no longer access the internet. However, all virtual machines are functioning properly and can access the internet without any...

Hello, I have several servers rented from my provider—let's say three, for example. Each server has an external IP address that I only use for configuration purposes via SSH (125.10.10.*). All servers also have internal IPs, which I use for internal communication between the servers...

Hello, I would like to set up an environment with multiple VMs running on a single server and assign an individual static IP for each of the VMs. The main server would be connecting to a single router with a public static IP. Is there even a way to do this? I am new to this so apologies if this...

I try to replace my routers DHCP Server with the ISC Kea Server in a LXC. As I'm new to this, I want to try it on a few client LXCs first. For this I want to block all DHCP requests that would go to the router and all DHCP requests that could reach the new DHCP Server from the outside of the...

Hi, I've got a strange issue with the last kernel 6.8.12-1-pve and my network card Sun ATLS1QGE. The card is drived by the "niu" module. Proxmox is constantly reporting for each interface connected "link down", and few seconds later "link up". I've got a lot packet loss, sometimes it was...

Hello, I've been trying to achieve this setup for quite some time, but without success. What I want is to configure vmbr0 as a bridge, which will use MASQUERADE for all VMs within the 10.10.10.0/24 subnet. It's fine for me if these VMs use the main IP address. However, I need one specific VM...

For testing and experimenting, I installed Proxmox as a virtual machine on my TrueNAS server and noticed that I cannot ping or access anything on my TrueNAS host from the virtualized PVE. My TrueNAS IP: 10.0.1.10/24 Virtualized PVE: 10.0.1.203/24 My TrueNAS network setup is straightforward -...

I have a proxmox cluster with two nodes with SDN VXLAN configured. Connections between containers and VMs work very well, also from different nodes. Unfortunately, I fail to connect the nodes themselves to this VXLAN. Could someone please help?

I was looking for many other similar questions but could not find any exact answers. In my case I have three server's ha network on 65 subnets and they are connected to one another using 10GB wire and ports. 1 VM is running on each node and is part of a cluster. I tried to tune my pacemaker...

Hello, I'm running in yet another problem! I have a Windows 11 VM on proxmox, this is pure for downloading. Everytime i'm downloading and the download goes around 30 mbps I get the following messeages: After this I lose RDP connection for a few seconds and Unifi tells me the device is...

Hey, I need some help... In my home network (10.1.0.0/16), I have a Proxmox server with a WireGuard LXC container. From this container, a VPN tunnel (10.7.0.0/24) is established to my second Proxmox server in a network at a friend's place, where I don't have access to the router. Therefore, I...

Hey everyone! I'm having quite the wild issue. I've created an LXC for Wireguard, for which I have also added the needed lines in the config of the LXC in itself as well as on the host, as per the OpenVPN installation guide. However, it seems I can't connect to it; what's more, in contrast to...

I did install 4 pve's version 8.2.2 and notice a issue on installation config. On install you can setup a netowork interface and the file /etc/network/interfaces became something like this: # so. # PVE will preserve these directives, but will NOT read its network # configuration from sourced...

Hi all! I have a Proxmox and AWX server and they are located on the same network with each other. AWS sees proxmox perfectly well and from it I can connect via ssh to proxmox, but I can't Ping or connect directly to the proxmox server from an external network, only via the web interface via...

Running the latest PBS as a stand-alone I've ran into an issue then machine becomes unavailable. Both console and network no longer respond. Sometimes console seems sluggish to respond, then stops. My observation and impression is this is after proxmox-backup-daily-update ran. To that end I...

Hello There, Is it possible to rate limit (network) an VM on a static value except for certain IPs so that the assigned IPs bypasses the network rate limit? Thanks in advanced!

So i've been trying to configure VLAN's for PROXMOX and VM's but i just cant seem to get it to work. An important information is that i am using a Fortigate 40F to configure the VLAN's, Policys, etc. Although i think my firewall config should be good. I think theres something wrong with the...

I have an issue with two Proxmox hosts which are misbehaving when establishing connections with pretty much anything. My own applications, apt, curl, ping, you name it. Both on the host and within LXC containers, things keep attempting to connect via IPv6, even though no IPv6 service is...

I installed proxmox on a vm with ip range 10.200.10.0/24 and on this range there is 1 DHCP server, then I created a vm using proxmox with vmbr0 but it does not grant dhcp ip to my vm, how do I fix it? What is this error and its cause? i fixediface vmbr0 inet static to inet dhcp I can't access...

Hi, I'm experiencing a strange behaviour on my PVE cluster with an LXC container. Context: I have a PVE cluster running on baremetal with version 8.1.3 with SDN Networking in place. I created an LXC container (Ubuntu22.04) on one host and I'm trying to reach the cluster API using Proxmoxer...
