vlan

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...

Hi, normally i dont make post, im use to spending a long time researching and getting the satisfaction of finding the answer myself. Im sure im probably already come across the answer but im unable to make it work in my lab environment. after hours and hours (probably over 20) of looking for...

Hi, ich habe Opnsense auf Proxmox laufen und zwei Interfaces auf dem Server: WAN (eth01 - vmbr0) und LAN1 (eth02 - vmbr1). Über Opnsense habe ich mehrere VLANs (LAN1 als Parent) konfiguriert sodass mein Switch der über LAN angeschlossen ist, Geräte zuweisen kann. Ich habe aber noch weitere...

Hi I have problems configuring proxmox on pure tagged vlan. I want put proxmox management on vlan99, and VM on vlan10 and vlan20. If I doesn't activate VLAN filtering with "admin-only-tagged" all work ok, but If I activate I can access to VM but no to admin interface. I try to put vmbr0.99 on...

Hi, I setup opnsense as vm. Opensense and host have separate ports to connect to lan. Both setup as linux bridge. I managed to setup VLANs on opnsense. they work beautifully with other CT on the same host. (I used tagging on CT interface) But it does not work anywhere else in my the network...

Hi Gang. I have a linux bridge vmbr0 configured on a 1g interface for management (192.168.99.0/24). The switch taking this traffic uses an untagged port to translate traffic to vlan id 99 (management vlan). This works fine and is the default route for proxmox to fetch updates, etc. I am trying...

help help help..... Situation setup: I want to setup a tinytuya lxc server. I have a udm-pro with several VLANS But let's stick to the one we need to know name vlan ip MGMT (the real one) 1 192.168.10.0/24 PROXMOX Servers VM or CT 15 192.168.15.0/24 IoT 20 192.168.20.0/24 Proxmox...

Hi, I have a pfsense vm in proxmox. pfsense: I have created a VLAN with tag=10 and the following interface assignments: - Management: VLAN 10 on vtnet1 - OBB: vtnet2 The firewall rules shall facilitate the routing between the 2 networks 10.0.0.1 and 10.0.10.1: - Management: Pass Any IPv4 from...

Got a host running PVE 8.2, that has a single NIC, eno0. A vmbr0 is also connected. The interface is physically connected to a switch port that is configured to carry LAN untagged traffic, as well as DMZ (vlan id = 100) and WAN (vlan id = 200) VLAN'ed traffic. Now, some VMs on my host should...
