Hi, Until today I had the standard Linux bridge vmbr0 with eth2 as the only bridge port - that worked fine. I now have a use case where I need an LACP 802.3ad bond between my main PVE host and my switch so I configured an active 802.3ad LAG port on the switch and added one of the spare 10GbE...

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...

I am having a problem where after an update, I lost all IPv4 connectivity. IPv6 thought works This is my setup: 1. Running proxmox on a mini PC (Virtual Environment 8.1.11) 2. Network layout Pfsense (router) --> Unifi Switch --> Proxmox MiniPC (172.25.90.50) 3. Proxmox server is on its...

Hello, (If this post seems familiar, I originally asked on the mailing list, but I'm posting it here for visibility) I've got a Proxmox server, and I'm wanting to use an A&A L2TP VPN[0] on the Proxmox host. I'm unsure how to set this up in `/etc/network/interfaces`, as I primarily use...

I have a small cluster with 3 machines - all Dell R720s. Proxmox was running well. I updated the least used machine to the latest version and ever since the network has refused to start up. I have been working at this for a week solid. I've read every post on the forum or the internet trying...

Turned out it was a problem on the Cisco end, I don't see where in running-config this is defined but evidently besides defining each vlan interface you also have to do "vlan XX" to activate the layer 2 vlan support for that ID. I think should should be a pretty simple thing to configure, but...
