vlan

Hello! So we're planning to migrate our vCenter cluster over to Proxmox, and right now we've got a test cluster setup using hardware that's pretty close to what we intend to order. We'd like to use SDN on our new Proxmox cluster, and based on everything I've read in the docs for Proxmox...

I replaced a node in my cluster with a new system and after getting the system up and running as well as a part of the cluster, I migrated two systems to the new node and now those VMs can no longer get vlan/IP configuration from the gateway. This was not an issue with the previous node that...

I am having an issue getting a pfsense DHCP relay to work across my proxmox cluster. My network is as follows: vmbr0 -> 192.168.12.0/24 - home internet (this is where my proxmox clusters are connected to vmbr1 -> 192.168.2.0/24 - virtual interface connected to a smart switch for VLAN 4...

I am having trouble configuring a VLAN VNet for my virtual machines using Proxmox SDN. After adding a zone and vnet I get the following error on some hosts: "error vmbr0" For example, the VMNet has the error on this host: But it succeeds on this host: All my hosts have the referenced vmbr0...

Hi. I need to feed 2 different firewalls, both with traffic from two different vlans. So I have 4 VMs to simulate the traffic. Both firewalls use the same vlan ids, but they are not the same l2 domains or IP networks. In other words: both firewalls relate to vlan 240 and vlan 250, but vlan...

I upgraded to a new server which has dual 2.5gbit NICs and I'm running VE 8.3.5. My router/firewall is a Unifi Dream Machine Pro and I recently switched to Zone networking. I'm looking to configure networking for this host as follows: The two NICs are bound together for load balancing Two...

Hello, I'm new here and, as expected, I have a question. :-) Is it possible to tag the Proxmox host interface AND the guest interface? Example: The Proxmox server has only one network connection (Linux Bridge), which is tagged with VLAN ID 120. On the guest system (Debian), three virtual...

Hi, I recently started working with Proxmox and I'm trying to configure subnets using vlan. I have only one physical network card and I reach my proxmox on the 10.10.4.0/24 network. I would like to create VMs on a separate network like 172.16.240.0/24 so I went to see the documentation to...

Probably a BUG in managing Vlans on renamed interfaces. I tried to rename the interfaces to get around the Bug of interfaces with too long names indicated in my previous post, but they are not seen and the Vm is not started. root@MSWstg4:~# cat /etc/udev/rules.d/70-persistent-net.rules...

If i try to start a VM: can't add vlan tag 12 to interface enp131s0f0.210 - the interface name enp131s0f0.210.12 is too long at /usr/share/perl5/PVE/Network.pm line 174. kvm: -netdev...

pve version: 8.3.4 ceph version: 19.2 I have only one physical network interface on my physical Proxmox server, so I don't have the opportunity to configure separate Ceph cluster and Ceph public networks. To work around this, I created virtual networks using Linux bridges on the physical...

If I put a Vlan tag in a vm on a host that already has the interface in bridge with vlan it generates an error. If I do it on an LXC machine, it also puts the node offline. Workaround, set the vlan tag directly in the vm conf file. pveversion -v proxmox-ve: 8.3.0 (running kernel...

I recently moved the proxmox host to a VLAN that I'm putting all internal services on slowly. I noticed that after I did that I don't get any emails for backups anymore and this morning I tried to update the packages for the host and it kept timing out. The host has internet because I can ping...

I'm running Proxmox 8.3.3 I have a Unifi UDM Pro on Port 6 is the actual cable to vmbr1 (192.168.40.7) and a cable on Port 26 from a UNIF 24 POE Switch. Both have on their port. Native VLAN / Network NONE Tagged VLAN Management Allow ALL I have a LAN-VM-LXC 192.168.40.0/24 VLAN tag=40 I have a...

Hello everybody, I have been using Proxmox for several years now, and I have recently been offered the opportunity to setup a 4-nodes cluster as a way to test things out. My setup is the following, I have 4 nodes each one of them have the following network configuration: - 1x Gbit NIC used in a...

I hava an ONU stick (consider it an ethernet cable or fiber) plugged to Proxmox VE host, let's say through eth0, it's like I connected to an hybrid port of my ISP which provides internet service with no vlan tag and VOIP service with vlan tag 46. I'm planning to host an Openwrt virtual machine...

After reading through PVE CM Redundancy, I am left wondering whether or not there is any reason not to use the same VLAN for the two separate physical corosync links? I see the example shows what presumably are separate subnets, but I see no explicit mention on whether or not such a logical...

Trying to wrap my head around how to implement a PVLAN within Proxmox. The purpose would be microsegmentation, so that each VM could not talk to each other without going through the upstream L3 device that has the Promiscuous Port configuration defined. Short of creating a VLAN per VM, is...

I installed the Proxmox VE on a physical system in my homelab last week for the first time (so I'm a noob in this tool stack). I know quite a bit about networking, but I'm not a networking expert/professional. I've used both VMWare ESXi and XCP-NG for quite some time to do experiments in my...

I am running an opensense VM in proxmox and while VM-VM throughput on the same VLAN can do ~32Gbps, routing across VLANs incur a 94% penalty dropping it to 2Gbps. I understand this is a limitation of emulating a L3 switch through software in which these devices typically have tailor-made ASICs...
