vlan

I'm trying to setup `vlan 33` with a single nic on my proxmox server. I have the below configuration on my `/etc/network/interfaces` file. auto lo iface lo inet loopback iface enp2s0 inet manual auto vmbr0.33 iface vmbr0.33 inet static address [redacted]/24 gateway [redacted] auto...

In the https://pve.proxmox.com/wiki/Network_Configuration page, under "VLAN on the Host" section, "Example: Use VLAN 5 for the Proxmox VE management IP with VLAN aware Linux bridge" shows the configuration for a single NIC and it's easy to understand. However the following snippet, starting with...

I'm seeing an odd scenario play out on a test pve cluster. The three pve servers have about 50% packet loss, dropping off the net for minutes at a time, but all VMs on them remain available at all times with 0% packet loss. Here's the network config from one of them: auto lo iface lo inet...

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've tried asking on ServerFault (https://serverfault.com/questions/1134269/where-to-put-vlan-interface) because it's not strictly a proxmox question. But I received no answers, only a suggestion to post on this forum, so I'm reposting here. I have 2 x 1 Gbps network interfaces. On top of them...

Hello everyone, I just recently set up two Proxmox-Servers (Intel NUC) and joined them into a cluster. Now I want to take the next step and separate my network into VLANs. I plan to set up a pfSense or OPNsense box (in Proxmox of course) which will service the VLANs. Both systems run the...

Hello, I'm having a bit of a hard time setting up my network right now. I have an Opnsense firewall running on the proxmox server. The server is connected to a switch and I can use VLANs normally. But now I have had the idea that I would also like to assign a VLAN to a physical port directly on...

good morning, have installed Proxmox VE 7.4 I am not able to do the following configuration with OVS. I have two cards eno1 and eno2, I need them to be in LACP bonding. These cards have vlan10 as their native VLAN and others such as vlan20 for the rest.I have tried the settings in the...

I have Proxmox 7.4-4 on baremetal server - it is fed with a trunk which I have working tagged on vmbr0. Within proxmox I have an ESXi guest VM to which I wish to provide the raw trunk vmbr0. I've successfully got it working by creating entries in my config eg: auto vmbr0.172 iface vmbr0.172...

Hi, i have a dedicated server on ionos, i need to have an additional public ip to one of my virtual machines behind proxmox. The additional public ip for this scope are delivered via vlan 1010 the additional ip is 217.xxx.xxx.164 The gateway is the same 10.255.255.1 so i have do this: auto lo...

Hi there, I’m using OPNsense as a firewall and VLAN. But I’d like to access (SSH mainly) the VMs at the VLAN from my LAN, but every firewall rule I make on the VLAN seems to block the LAN. Ping or SSH from LAN results in a time-out. What am i doing wrong? Firewall rules VLAN below: Pic1: I’ve...

I was messing with one of the nodes on my proxmox cluster and experimenting with putting the management interface/GUI on it's own VLAN, and in the process managed to completely kill the network connectivity on the node even after undoing all my changes. I'll try to explain in a series of steps...

I have a proxmox node configured with several VLANs on the same physical interface connected to an HP managed switch (HP-A5120). I was using VLANs 100 and 101, each with it's own LAN addresses, on several VMs with no problem. I added a new VLAN (4093) and two VMs within proxmox see each other...

Hi I have 2 proxmox hosts, and I would like to make a CT thats just for docker, my requirements are to have 3 VLANs in the docker CT, which are the LAN, IoT (2), and an isolated VLAN (100). seems simple right? I have configured 2 networks on the CT: eth0 is the LAN network, eth100 is the...

I look for support and guidance around where I am going wrong in a PROXMOX environment that I am setting up. I have one server that is connected and working for the Test Environment. It is running on the 172.16.0.15/16 network. We have three more servers that we have set up in cluster. The...

EDIT: Nevermind! Turns out I didn't notice I was changing the NIC definition inside a snapshot, not in the base VM itself. When I changed the definition in the base VM it started working! Hi. I'm having some trouble getting multiple VLANs working on a NIC in a VM. I'm trying to use both a...

Hello everyone, I have some servers on OVH connected via vRack. actual confuguraton: there is a vm inside hyper-v with opnsense, this one act as router and firewall. Opnsense gives addresses (no dhcp enabled) to all the entity in the net (hypervisors and vms), at the moment opnsense works only...

Hallo Zusammen, ich stehe im Moment total auf dem Schlauch. In großen Netzwerken gibt es in der Regel eine DMZ und in dieser immer eigene Hyper-Visor für spezielle VMs, welche von Extern (aus dem Internet) erreichbar sein sollen. Hier gibt es dann auch meisten größere Firewalls, welche den...

Hi! First post here. I did a lot of research before asking. I have a single node Proxmox host using a vlan aware bridge. The switches are properly configured. I can install Debian using the ISO and configure a single virtual interface linked to vmbr0 on the host and manage multiple vlan on...

Hello! I'm having a hard time getting VLANs to work properly on my new Proxmox cluster. Hopefully someone has some suggestions to get this working. In short, it seems that Proxmox isn't properly passing tagged packets to my VMs. Example VLAN 542 (10.0.42.0/24): I have a secondary 10GB NIC...
