dhcp

Good afternoon, I would like to know what else I can check to help my VM connect to the network. I installed Proxmox under Debian following the wiki (https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_12_Bookworm) and created the Linux Bridge vmbr0. However, when I create a VM using...

I want to use SDN's DHCP to assign IP addresses to the virtual machine's tap device, but I find the dnsmasq config file which managed by PVE itself has this optiondhcp-ignore=tag:!know. So if the MAC address is not in the list of addresses assigned by PVE, the DHCP server can only receive the...

I have a working Proxmox 8.3 server in my homelab - the standard recommended setup. The Proxmox instance has a static IP address and the IP has static lease in my router (OpenWRT 23.05). I use only ethernet connections. I set up few VMs and LXCs configured them to use DHCP and created static...

EDIT: SOLVED. So apparently my 10Gbe sfp on my switch for that subnet crapped out. Lesson learned to keep a couple extra on hand. now to look into if there ways to monitor that it was failing. I did notice later last night when working on one vm that things were getting slower to respond on my...

Greetings to everyone, I'm kinda new to ProxMox, but I'm struggling with an issue which i don't know if it is possibly or not. I have my PVE node, hosted and set on the static IP x.x.x.100 configured by /etc/network/interfaces. Then, I created a VM installing on it Pi-Hole, setted on...

I try to replace my routers DHCP Server with the ISC Kea Server in a LXC. As I'm new to this, I want to try it on a few client LXCs first. For this I want to block all DHCP requests that would go to the router and all DHCP requests that could reach the new DHCP Server from the outside of the...

Hello! I have Proxmox VE running on my laptop (8.2.4). I have a standard Linux bridge with the configuration of this auto vmbr0 iface vmbr0 inet dhcp bridge-ports enx0222796c7c62 bridge-stp off bridge-fd 0 which works great, except for when I restart the node, anything connected to...

TBH, I am a little bit confused. Cluster, 8 nodes, dedicated VLAN for QinQ on a sync interface. 1. Created a Zone, VNet, Subnet 2. Linked PhpIpam 3. Did installed dnsmasq, though it should work only for a simple zone, according to the fineprint in docs. If I configure VM IPs as static in VM...

I installed proxmox on a vm with ip range 10.200.10.0/24 and on this range there is 1 DHCP server, then I created a vm using proxmox with vmbr0 but it does not grant dhcp ip to my vm, how do I fix it? What is this error and its cause? i fixediface vmbr0 inet static to inet dhcp I can't access...

I use the DHCP server in the OPNsense FW (23.x) It runs as VM on separate PVE Node [7.x.x] The new PVE Node [8.2.2] has two interfaces One interface ETH0 is used as PVE Management bridged by VMBR0 and has a static IP on the same network as the OPNsense FW (192.x.x.1/24) The other interface ETH1...

Hi everyone, I have a very strange issue that I can't figure out how to solve vmbr0 is the lan bridge, I have another port (2.5Gbit/s) on the router that I wanted to switch along with the main one (10Gbit/s), as you can see from the picture, so that I could connect the ubiquiti AP to that (as I...

Hi Proxmox Community, I know this is a long post but I'm trying to be as detailed as possible with the steps I have taken. I have some live VMs on a VMware product as I'm trying to move over to Proxmox for everything. I'm running some VMs on Ubuntu OS for websites using Apache2 and I took a...

Still learning here.... I have four NICs each connected to a different network - connected to a UniFi Switch (vlans configured via UniFi switch). I am confused on how to define the bridges to allow DHCP for each NIC and also allow the PVE host to access them. My current Network Setup is...

I have firewall enabled on the datacenter level. When setting up simple sdn with DHCP. Created a new VM, but DHCP address is not getting assigned to guest. If i disable the firewall, I am able to get a DHCP address without issue. Im assuming i need to add a firewall rule to allow, just not...

Ich möchte meinen Windows Server 2019 Domaincontroller, der derzeit unter ESXi 6.5 läuft, zu Proxmox migrieren. Es gibt keinen anderen DC im Netzwerk. Bei den Vorbereitungsarbeiten lese ich: "On Windows, consider removing the static network configuration, if there is any. After the migration...

Hello. This week I bought some fresh hardware for my home lab, made a fresh Proxmox installation, and am now facing a weird issue. I have a 802.1Q VLAN-separated network at home. The server's NICs are plugged directly into the router. The server has 2 NICs: - one integrated in the mobo which I...

My physical hardware is an Ubuntu laptop and the nesting is as follows : Linux Mint: "Linux Mint 21.3" proxmox: installed from proxmox-ve_8.1-1.iso VirtualBox: Version 7.0.16 r162802 Ubuntu: "22.04.4 LTS (Jammy Jellyfish)" For the most part things work well but when I boot the Mint VM, it...

If you set a VNET on a "Simple" Zone, it allows you to set a dhcp range. For this to work, it must also have a "gateway" ip set, even if you are not planning on talking out. The "gateway" is the host IP that the dhcp server listens on.. When this is created it tests for the existence of the...
