networking

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...

All - I know there have been many posts regarding similar issues - and I apologize for positing if this has already been addressed - but I've been trying to shift from ESXi for five days and am at the end of my rope. For background I've been running ESXi homelabs + Unifi infrastructure for...

I have 5 IP addresses from my ISP and need to setup a VNET for each IP with a pfSense firewall to provide UPNP support for each IP. My test machine has a an internal Ethernet port and a USB Dongle. I am using the dongle (enx22) for the WAN The network looks like this: enx22 <--> vmbr1 <-->...

Hi, I'm new to Proxmox, I've tried Googling this without finding a workable solution. I'm trying to do something (relatively) simple; and I'm not familiar enough with Proxmox and networking to know whether this is something that is done via the Proxmox GUI or customising Linux config files...

Hi everyone, I’m facing a strange and frustrating issue with my Proxmox setup and could really use some help. Here’s the situation: • Randomly, Proxmox becomes unreachable via web GUI or SSH, but all the guests are still running and reachable without any issues. • When this...

Hi there! VMs can't ping route after pve restart networking.service and won't able to reconnect automaticlly. I have to toggle firewall flag of network device net0( enable firewall if it is disable, vice versa) to resume VM's network. Impacted VMs' system are debian12 and win10. Neither...

So it has been a **long** time since I've done anything with the networking on my proxmox ve setup. For reasons that I have no recollection of (other than maybe 'sounds cool!') I went with openvswitch. I now need to do some vlan work. When I open /etc/network/interfaces the first thing I...

Here's my config, and forgive me, I'm an "old" vSphere admin: auto lo iface lo inet loopback iface eno1 inet manual iface eno2 inet manual auto ens2f0 iface ens2f0 inet manual auto ens2f1 iface ens2f1 inet manual auto bond0 iface bond0 inet manual bond-slaves ens2f0 ens2f1...

Hello, this whole shebang has already taken me nearly a week to try to figure out, but I'm still stuck. Background: I want to spin up a 5 VM Docker Swarm cluster. They're meant to be using keepaliveD for HA/Failover using a simple SDN. That seems to be working OK. Now I "only" need peristent...

Hi Everyone, So the Proxmox server got itself a reboot today for the first time in a while, and when it came back up, there was no network connectivity. The PCI device appeared in lspci, and the network device appeared in "ip link show". ifconfig showed only the vmbr networks, and they were in...

Hello, my provider do not offer any additional ip, so can I buy a ddos protected ip from some other provider and from the vps I can configure something and add it to my proxmox? is it possible this is the only way I can get ip for my Proxmox server this will help me a lot thank you! kindly...
