networking

Hello, I have four Proxmox servers, updated to the latest verion. Each have their network configured in the same fashion, with multiple network cards, which are either not getting an IPv4, getting one by DHCP or one, vmbr0, having a static assignment. On vmbr0, each server has its own IP within...

I'm in need of some help from some of the seasoned professionals out there. I'm setting up a 5-node cluster with Ceph that will run around 30-40 VMs. Each node has two 4-port 10G NICs. I'm going to use LACP to bond one port from each NIC to create four connections on each server. However, this...

When importing an Ubuntu cloudimage VM from VMware I noticed that the networkinterface name has changed, and potentially happens again in the future. So I want to make it static inside the VM. Context is that the VM originally is configured by VMWare's Cloud-init approach (...

My server was struck by lightning..... Ouch. Since then I have been busy moving and such. I have just powered on my Supermicro X10SDV-12C+-TLN4F system after many months. After loading the new system I was unable to access the server via any browser except an old Windows 7 Pro OS which had an...

Hey guys, I'm looking to port forward my proxmox and access via WAN so I can access Kali VM. Can anyone provide any guides I can use to do so? Everywhere I've looked I haven't found a sold or updated tutorial on doing so, I have an Arris BGW320 router Thanks in advance!

Hello, I am using Proxmox 8.3.3. and after a reboot I cannot access GUI, cannot ping proxmox or any VM (VMs are not online as well). I can reach proxmox server over SSH anr Winscp. There are no errors (I went through previous threads on this subject and all rights to folder and certificates...

My Proxmox host has great network connectivity. Before I rebooted it, my LCXs and a single Win VM all had similar. After a recent update and reboot, my containers and VM are all under 1 Mbps. /etc/network/interfaces auto lo iface lo inet loopback iface enp2s0f0np0 inet manual auto vmbr0 iface...

Fresh install of Proxmox (version 8.3.5) on a Dell T620 with 256 GB of Memory on a 1TB SSD. Boot sequence is great and I am able to reach the Proxmox web GUI, but after some amount of time initially it was 30ish minutes now it seems to get to about 6-12 hrs then the ethernet connection is...

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...

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...

I’m running into an odd issue with my Proxmox server (version Virtual Environment 8.3.4) after a power cut. Both the server and my router restart automatically when power returns, but the server doesn’t connect to the network properly until I manually restart it. (i already configured the dhcp...

Hallo an die Proxmox-Community, Ich brauche Schwarmwissen, denn seit ein paar Wochen (fällt es mir zumindest auf) kann ich von Clients hinter einer Router-VM die IP des Routers (`prefix::`) nicht mehr pingen. Und nach Paketanalyse auf der Bridge und auf den VMs selbst, gehen zu dieser IP auch...

On one Linux Client, ip -6 neighbor lists the Proxmox VE Host(s) as Router, when they clearly are not: 2XXX:XXXX:XXXX:1::A:B dev eno1 lladdr 11:22:33:44:55:66 router REACHABLE Setting sysctl -w net.ipv6.conf.vmbr0.forwarding=0 on the Proxmox VE Host fixed that, but I wonder if that also caused...

Hello and happy new Year! My idea for setting up networking was to have vlans tagged by hypervisor, so the VMs are not really aware what network they are on (someone told me it's an overkill for a homelab, but I would rather follow best practices when I can and that feels like a better thing to...

Hello there, people! Is it possible to create a Proxmox cluster using VLANs when the servers are on different subnets? Here’s my setup: Main Server: - IP Subnet: 192.168.1.x - Runs behind a router (192.168.1.1) - Has 2 NICs available New Server: - IP Subnet: 192.168.101.x -...

Hi, Fixed: Need to have >1 interface in the LACP bond before it'll work with vmbr0. Yes I know a single interface defeats the purpose of LACP but the LACP bond works fine with a single interface UNTIL it is added to vmbr0 as a bridge port. ----- Until today I had the standard Linux bridge...

Recently did the 11.2024 update. After a reboot, one of my server's VMs (primarily Linux) no longer has connectivity to the network. I am passing VLAN tags through to the VMs using a 2 bonded 10Gbps NICs. The server is part of a 2 server cluster with a Quorum Member. All the interfaces on the...

Hello, I was wondering if there is a way to direct any traffic (ssh,mysql etc) from a subdomain to a specific machine with haproxy. The problem is I have multiple Proxmox machines under one Public Ip and I want to access every machine with its own subdomain remotely.

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 everyone, I'm new here, basically this is my first post on this forum, and I do have an issue with my Proxmox. I do have two proxmox servers in cluster and, I try to add a Windows VM (from NODE1) to a domain, which is on NODE2. Unfortunately, there is no connection, the nodes have connection...
