Hello! I am not sure if I have followed the instructions on various sites properly but here is my setup, and the items I have done. I do want to note that my proxmox server is in a cluster with 2 other nodes (3 nodes total, and they are on 10.0.0.0/25 subnet at the moment with no VLAN attached...

Hello PVE enthusiast, I am currently administering 4 Proxmox nodes and each one is siloed so there is no direct networking between nodes. the network setup on every node is the same (it's the basic bridged network that i saw in every PVE setup tutorial): These are the linux bridges that i have...

I have a bare-metal Proxmox server running with two public IPs. The initial configuration has already been done, and the containers are running with a NAT and a private network. I currently have 2 public IPs: 190.140.147.92 (This is the available one) This one has a comment in the interface that...

I am trying to setup a Debian 12.1 (Bookworm) LXC CT. The container starts but it takes about 5 mins to get to a login prompt. Once the login did appear I ran apt update / upgrade and rebooted to the same issue. Upon inspection, systemctl shows networking.service has timed out. The network is...

Hi Folks, Does anyone know what might be going on? I'm seeing vmbr0 flipping into and out of promiscuous mode, until, eventually (< 1 hour), the machine becomes completely unresponsive (even from the console) and I have to power cycle/reset the machine. Debugging is a bit challenging, since the...

Hello Proxmox forum I've recently setup a proxmox server as a test environment but having a challenge with connectivity. I can SSH to the VM but can not get HTTP to work despite the service being active and responding within the VM. This is the bridge that I'm using: auto vmbr0 iface vmbr0...

Hello fellow members. My sincere regards. I disturb you because I didn't really find valuable resources, and I'm failing to understand how to configure my 6 NICs to suit my needs. Specs: Intel 3865U (active VT-D and AES-NI) 4Gb DDR3 1600MhZ (single slot) 6x I210 Intel NICs 512GB 2.5" sata SSD...

I made a mistake when I created a 5-node cluster. I added all nodes by IP to the cluster and `pvecm status` now shows: Cluster information ------------------- Name: cluster2 Config Version: 5 Transport: knet Secure auth: on Quorum information ------------------ Date...

Hello, I'd like to create an isolated network within proxmox that has 2 or more VM's within it that can talk to each other as in transfer files and so on, but otherwise have no access to the wider network so can't access the internet or any machines outside of the isolated network. Could...

We ran into a very nasty issue a few days ago. Background: Systemd generates ridiculously long interface names (see https://manpages.debian.org/bookworm/udev/systemd.link.5.en.html and referenced here https://wiki.debian.org/NetworkInterfaceNames#CUSTOM_SCHEMES_USING_.LINK_FILES) like...

I have a very strict firewall policy that essentially boils down to, block ALL traffic from any and all servers and computers that are not essential to that host's operation or needs. This seemed fine for a while but I just realized that anything on VLAN 10 can access Proxmox via SSH, even...

Hello, as you can see, below I have attached a diagram of my home network and I have some concerns. I want pfSense, which will run on a VM from the Proxmox server, to be the main router (Wan PPPoE, DHCP for all devices, to provide me with Internet for the Proxmox server for the rest of the...

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 followed the guide https://pve.proxmox.com/wiki/Renaming_a_PVE_node, and renamed my main node, and also my cluster name. When trying to move a vm back to the newly named node, I get the error 2023-09-04 21:09:39 # /usr/bin/ssh -e none -o 'BatchMode=yes' -o 'HostKeyAlias=ravenclaw'...

Hi folks, It's time for some tinkering with the home server and network. Before I embark on my journey, I would like to hear your thoughts about any pitfalls or dos/don'ts you can see in my plan. Please let me know your comments or tips on the below. The WAN uplink is provided by my ISP's...

Hi, I am trying to configure my Proxmox VE server to use Bonding, VLANs and make the VMs/CTs run in "routed" mode. I have successfully configured the Proxmox VE host to use bonding and VLAN on the host. However, I am currently stuck configuring vmbr0 interface for routed mode. I have used...
