networking

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...

Hello, As a new user of Proxmox, I've installed it on a virtual machine running on a Hyper-V server (with the goal of exploring Proxmox and potentially migrating my server fleet to Proxmox in the future). I'm having difficulty setting up VMs (tested with Windows 11 and Debian 12) because I...

Hi everyone, I have 4 nodes in my Proxmox Datacenter. Two nodes are in North America and two are in Asia, thus they are both in different geographical locations and networks. Node 1 (10.10.100.1) Node 2 (10.10.100.2) Node 3 (10.100.200.1) Node 4 (10.100.200.2) I have successfully setup Ceph...

Hello, i have the issue that on one proxmox machine the label internal is showing with "ip a" and on the other machine it isn't. I got two proxmox installations where i configured the following: auto lo iface lo inet loopback auto eth0 iface eth0 inet manual auto vmbr0 iface vmbr0 inet...

I have been trying to setup pfSense but I accidentally set the pfSense vm to the integrated network controller on my server (one of the 4 ports on a dell r720). I have already run (VM number is 104) qm stop 104 qm destroy 104 Any help is appreciated!

Hi all! I recently installed proxmox on my server, and now I'm trying to get networking in order. The problem that I have, is that for a certain VLAN, the DHCP response from my DHCP server doesn't seem to end up in my VM. It does seem to reach proxmox, but there's nothing arriving in the VM...

I know this is a bit of a long-shot but maybe there are some others with similar use-cases. Right now Proxmox has integrated support for virtual-eth networking to containers and it works well. I really want to be able to add interfaces to a container for network devices other than Ethernet...

Hello, We have a Proxmox server setup in our datacenter with a local network configured for the host (Proxmox GUI) and we have a second VMBR setup named VMBR1 with a Linux BOND for failover to access our public IPS. Now I was wondering, how could we prevent that our CT/VMS can ping our local...

Hello Everyone, I'm sweating my bal*s off right now, i've been searching for a definitive and working answer for days but nothing seems to work. To start i use the onboard motherboard NIC as the main one, which is on 172.168.1.0/24 LAN, which is also working fine as intended. As a second NIC i...

Hi, let me describe my use case first. I have a remote physical server of around 20TB. I want to use it to host my web app which is currently in GKE. So I want to configure my physical server to host my web app, I'm planning to install a hypervisor (proxmox) on my server and host VMs. Doubts...

I am self-hosting Proxmox VE v7.4 and have a Windows 11 VM configured with a SPICE display and SPICE enhancements enabled. I've installed both spice-guest-tools and spice-webdavd on the VM to enable folder sharing and I can connect to the VM just fine using virt-viewer on my local network. I...

Hello, I'm encountering an issue with accessing the web interface of my Proxmox server. Here's my setup: I have a Dell R710 server running the latest version of Proxmox, and I recently installed pfSense as a VM on it. Currently, pfSense is the only VM running, and it is connected to the...

I recently got a 10G NIC (Intel X540-T2). The plan was to run one port directly to my workstation and the other directly to my Windows server. I configured each port to have their own Linux Bridge and static IP on a separate ip range from the rest of my home just for this 10G, computer to...
