vlan

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...

Hi all, am new to Proxmox and wondering how I can setup several VLANs for one guest-VM. This guest VM will be used as proxy and firewall between several networks. So, the server itself has two hardware interfaces. Interface 1 is used as the mangement network port Interface 2 shall be used for...

Hello, I am having a hard time accessing my Proxmox server. I have one router sitting between my computer and the Proxmox. The Proxmox is connected through 1 physical cable to the router, which is configured as a VLAN trunk port with VLAN 10 and 30 configured. For VLAN 10, I am using the network...

I have been troubleshooting for a long time and I feel I get more confused the deeper I try to troubleshoot. my pve node resides in vlan 20, which is tagged. My PVE can NOT ping gateway 192.168.20.1 A container in vlan 1 (management), can ping its gateway. This vlan is untagged A container in...

Greetings. We have a cluster with the following network configuration, most of which is working correctly but when I try to add a second NIC to a VM it can't see the network. Here's the network layout: Host level - everything works here: bond0 (used for management only) bond1 -> bond1.110...

TLDR: No DHCP offers from pfsense with VLAN tagged on a VLAN-aware host. Switch is trunked to allow "All" traffic. I have a VLAN tagged as 20: https://i.imgur.com/Rz61DMz.png And its corresponding interface: https://i.imgur.com/pQxJitG.png And its DHCP server: https://i.imgur.com/jsAjxid.png...

Hi I have a proxmox cluster(datacenter) with 5 hosts and want to add VLAN on all of hosts Is there a way to add VLAN on datacenter not in each hosts? Best

Hello, I'm trying to migrate from vlan to vxlan, and I'm trying to figure out how to best bridge between a vxlan and a vlan. My initial thought was to use a linux vm and just bridge between two interfaces. While this will work, I'm wondering if there is a better way to do this? I know that it's...

I have a Proxmox server, and I want to add VMs to this host so they can communicate with each other on a private network using eth1 and have internet access via eth0. On this host, I have vmbr0 with the following configuration: auto lo iface lo inet loopback auto vmbr0 iface vmbr0 inet...
