dhcp

Hi I installed pi-hole on a VM on Proxmox and enabled DHCP. All other VM's und CT's on Proxmox can get IP addresses. But other hosts in my home network do not get a IP address. All firewalls are disabled in Proxmox. Any ideas? Thank you

Need some assistance setting up a proxmox SDN subnet with DHCP. I've got the following configuration: tldr: subnet called `nexus` with range `10.10.0.0/24`. Gatway `10.10.0.1` and DHCP range of `10.10.0.{20-254}` root@goliath:~# tail /etc/pve/sdn/*.cfg ==> /etc/pve/sdn/subnets.cfg <== subnet...

Hi Everyone, As an exercise, I have a 3node cluster running a simple SDN setup. I disabled autoDHCP and setup a windows DHCP server. When I install a client machine on a different node it is unable to get DHCP but when I migrate it to the same node as the server it works. I have disabled all...

I have a Proxmox VE 8.3.0 running on a machine that has a single, statically configured IP address. Guest OSes do not have Internet access. How should I set up NAT and DHCP on a Proxmox host to provide guest VMs with Internet access? There are multiple tutorials over the Internet, but many are...

Hallo Ihr Lieben, ich habe mir ein Proxmox Server installiert. Dieser Server hat 2 nvme Disk mit jeweils 1TB. Auf einer Disk ist das Hostsystem installiert. Dann habe ich noch 2 Stück 12TB SATA Festplatten die in den HotSwap Schacht stecken. Diese sollen als Data Storage dienen. Weitere 10...

I am running a Proxmox Cluster in a nested Hyper-V environment. After the installation I login and create a Windows VM and assign "vmbr0" as the Network device. But inside the VM I am unable to get an IP address. The Proxmox is connected to the network and is able to access the...

I'm trying to setup a isolated VLAN network with SNAT so containers and vm's can reach out to the internet. Using SDN I: Set up a VLAN zone connected to vmbr0 Created a vnet connected to the zone with tag 100 Created a subnet connected to the vnet with subnet 10.10.10.0/24 and enabled SNAT...

Apparently my LXC is not renewing DHCP leases. From time to time the IP address gets released and `eth0@if9` loses the IP. I can't figure out why. I've seen similar posts and have been trying to fix it with no success. I used to have 3 network interfaces set in the Proxmox UI, but recently...

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 trying to install px ve 8.3 on a couple of Dell machines using Idrac's virtual CD option. This works fine when Idrac is on a dedicated port. However, some of the machines use a shared Idrac port. On those machines the Idrac / virtual CD connection is lost when px installer probes the...

I have a pve 8 standalone node that came with the regular vmbr0 and vmbr1 bridges. When creating VMs and attaching them to these bridges everything works perfectly. I decided to use Proxmox SDN to have better native control over my subnet configuration. For this, I have done as the docs said...

Hallo zusammen, Ich bin absoluter Neuling. Ich habe mir Proxmox installiert und versuche gerade einen Container zum Laufen zu bringen. Der Container hat jedoch keine Internetverbindung. Er wird auch nicht in meiner Fritz!Box aufgeführt (DHCP aktiviert). Ich kann nichts pingen (auch nicht die...

I have connected Teltonika TRM500 usb-modem to Proxmox, configured and mapped to interface wwan0, it gets a public ip from DHCP (no static ip available). I get connectivity to Internet from VE CLI. What I want to achieve is to passthrough wwan0 connection to a VM running Opnsense. So I have...

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...
