vlan

I am planning to improve the network setup for a small Proxmox VE homelab & wanted some advice from more experienced users here. Right now the setup is quite basic with a single NIC and a standard Linux bridge configuration. It works fine for simple testing, but I am starting to look into VLANs...

Hallo Zusammen, ich arbeite sehr viel mit Vlans für die Netzwerksegmentierung und auch wegen der Sicherheit. Bisher habe ich die meisten Erfahrungen mit VMware und Hyper-V und stelle mich jetzt langfristig auf Proxmox ein. Ich bin gerade dabei ein Proxmox Cluster aufzubauen und dabei kam mir das...

Hi, while playing around with Proxmox and Unifi I was thinking why it is not possible to have VLan IDs and there given names be synced between Proxmox and the FW/Network controller. As I use Unifi my first search was for there...

Topic says it all. But first let me introduce the topology: PVE Host connected via LACP (bond0) to a core switch pair (QSW-M7308R-4X) MLAG trunk port. Trunk port has PVID 1 and IDs 1600 and 1702 configured. This configuration is known to work as there's an Access Switch connected exactly the...

Hallo Zusammen, ich muss den Zugriff auf mehrere VMs auf einem Proxmox Host übers Internet freischalten. Als Firewall ist eine OPNsense auf einer eigenen Hardware im Einsatz. Außerdem soll ein Reverse Proxy auf dern OPNsense eingerichtet werden. Vlans sind auch im Einsatz und werden noch...

Hello there, at my wits end on this one, since I cannot really find a reasonable explanation for this: a cluster of 3 proxmox nodes, each with 10 network interfaces, bonded in pairs with 802.3ad comprising 5 networks that have 7 VLANs in total Not using all that SDN stuff, mainly because I have...

BUG: VM with tag=1 on VLAN-aware bridge — traffic exits bond0 untagged, VLAN 1 broken when native VLAN ≠ 1 Hi all, Spent ~13 hours troubleshooting this with Claude.ai after a power outage took down my homelab. Documenting here as it appears to be a known limitation in Network.pm that isn't...

Hello all! After 3 days of digging, I decided to ask directly: My proxmox host is connected to a Unifi switch port with a native VLAN 1610, also allowing tagged VLAN traffic for IDs 3510, 1620, ... That means the proxmox host is automatically in the 1610 VLAN. Setting up single-NIC VMs has...

Hallo, ich beschäftige mich noch nicht so lange mit PVE. Allerdings soll es nach vielen Jahren Problemen mit Synology und Co im Heimnetzwerk nun mit Proxmox in die nächste Runde gehen um das auf bessere Beine zu stellen. Meine Fragen drehen sich im Moment um die Einrichtung des Networks auf den...

Hi all, I want to use a nic in vlan aware mode to connect multiple phisical devices. Below is my networking diagram. vmbr0 and vmbr1 are working fine, i'm not able to configure vmbr2 (LAN in vlan aware mode). This is my network interface: auto vmbr0 iface vmbr0 inet static address...

I'm trying to setup VLANs on proxmox, and many tutorials start by creating a management VLAN. My default interface is: auto vmbr0 iface vmbr0 inet static address 192.168.50.50/24 gateway 192.168.50.1 bridge-ports eno1 bridge-stp off bridge-fd 0 bridge-vlan-aware yes...

Hi, I'm running PVE 9.1.4 in a 3-machine cluster using Mini-PCs. My scenario is this: I have a 3 VLANs: VLAN 1 : 192.168.2.0/24 - switch network. I have to have this one because the switch I have doesn't like to have its IP or VLAN changed, so I'm stuck with that. VLAN 10 ...

Hi everyone, I’ve just registered on the Proxmox support forum and I’d like to ask for some advice regarding managed network switches that work well with Proxmox, especially for VLAN usage. To give some context about my setup: I currently have 3 Intel NUCs and one GPU rig, all running...

I have the following network configuration: an ISP router connected via cable to the server’s network port eno1, where Proxmox is installed, and a second port eno2 coming out of Proxmox that will be connected to a switch for network management (VLANs, etc.). Nothing is connected on the outgoing...

Hi, I want to create a VLAN in my Proxmox, I have a router provided by my ISP and all of it's ports are used, one of them is connected to my Proxmox server. By checking my ISP router, it's seems like id doesn't support managing VLAN's. The goal is to have my VMs and LXC containers on their own...

Hi members, I have been recently faced with some issues setting up vlan on the promox machine at same time, passing those vlans to my virtual machine 1. I setup two sub interfaces facing a switch wich split the management traffic and internet traffic for the proxmox 2. so, It means, proxox...

Having issues with VLAN connectivity on my Proxmox setup. My Ubuntu VM is getting an IP address, but it cannot reach the internet. I’m trying to figure out if my VLAN config is wrong or if I'm missing a route/gateway somewhere. Also vlan are set in OPNsense. Here’s my...

Hello everyone, I am currently trying proxmox with opnsense as a VM and trying to understand more the VLAN functions und firewall rules. I have made a config and it is working but I am asking myself why some things work and some don't. Maybe one of you can answer them. 1. Why am I able to...

When a VM is assigned a bridge interface (VLAN aware) with a VLAN tag on the interface and this VLAN also exists as a VNET (same bridge and same VLAN tag) AND is assigned to a VM AND VMs are spread over different hosts, the VM with the bridge assigned directly get all the traffic of the VLAN of...
