I run OPNsense as a FW, I have a 4xPort lacp to my main switch also 4xPorts lacp which all my Vlans go through. from my switch to my proxmox server I have a 2xPort lacp. I cant get Internet access or ping any other Vlans/devices from Container or VMs that are not on the main proxmox-mgm...

Hey everyone, this setup runs in a datacenter on a public IP 37.x.x.86/26. The server has got one physical interface eth0. The current setup works nicely with a masqueraded private subnet 10.10.10.0/24 and the single public IP. I now bought two additional IP adresses, because i need public IPs...

Hi, I'm having an issue where I cannot add new interfaces to VMs, or even create new VMs, because proxmox lists my vmbr0 bridge type as 'unknown'. This means that I have no devices listed in the 'bridge' option box when creating interfaces or VMs, and therefore they cannot be created. I can...

Hi guys, Got a question about internal networking between VMs. I've created a secondary Linux Bridge (vmbr1), and I'ved added the bridge to three VMS; two win10 vms, and truenas. I've assigned a secondary IP for each o the vms: 192.168.2.1 = Truenas, 192.168.2.2 = Win10VM1, 192.168.2.3...

Hi, I wanted to try nftables on Proxmox, it seems quite nicely done, bravo! I guess most users don't use any output filters, but if using them in iptables, we get a stateful output rule, allowing to only open INPUT for a given port, and assume that it will go out. Chain PVEFW-HOST-OUT (1...

Alright context. I have 2 nodes in a cluster. Dell R620 Dell R720 Going to talk about 3 devices total. All have 10Gb networking to each other through a switch Both machines are running the same pve version (8.1.10) and kernel versions, both are fully up to date Both machines have the same...

I created a Proxmox server on VMWare as a sort of development environment/ for experimenting to test if my idea works or not before moving it to the actual physical device. I am also using GNS3 to simulate connecting to a switch and then to another VM (external device). Some terms I use for the...

Hii Everyone, Actually recently i've setup a proxmox server as my first home-lab. Please consider me as an guy on its initial stage of learning networking and homelab. So, I'll come directly to the point. I'm planning to create live-streaming server for my so called "Business Idea". In my...

I'm another vmware admin who's looking at Proxmox as a potential transition option. I'm not doing anything particularly intensive, I just deployed a few hypervisor VMs (under ESXi) to get a feel for the system, deploying VMs, networking, etc. Everything is working fine so far, other than the...

I have three Proxmox 8.1.4 nodes. I have one VM (VM1) on node 1 and one VM (VM2) on node 2. I need VM1 to talk to VM2. Each VM is using a network bridge called "vmbr5" defined at both node levels. Using the SDN functionality, I know using a "Simple" Zone is not the way to go. I am now trying...

Moin, habe ein Verständnisproblem ... habe Proxmox 8.1.4 auf einer IPU mit 6 NICs laufen ... Auf PVE eine VM mit pfSense, welche meinen Datenverkehr regelt. Das tut diese seit längerem auch verlässlich. cat /etc/network/interfaces auto lo iface lo inet loopback iface enp1s0 inet manual...

Hey all, I am having an issue getting connectivity to my VMs. I have a USB wireless adapter for Wi-Fi connectivity to my internet. When I try to make a Linux bridge from Wi-FI adapter <--> vmbr0 to have a VM bridge, it changes my default gateway / routes and I can no longer access my server from...

Please help. I did it like here (Masquerading) https://pve.proxmox.com/wiki/Network_Configuration. i have only one public IP. Proxmox version 6.4-1. $ cat /etc/network/interfaces auto lo iface lo inet loopback auto ens3 iface ens3 inet static address XXX.XXX.XXX.171/24 gateway...

I'm quite unsure of what is happening. I've been struggling with this for the last two weeks. So I've installed proxmox on my home machines. My gaming PC has a GPU passthrough working well enough, and my Windows VM feels like a natural PC with all my USB ports forwarded and everything. I even...
