network configuration

Hi I'm new to Proxmox and try to create VM which is ubuntu 24.04. The problem is it can not connect network bridge (vmbr0). This is proxmox's interfaces auto lo iface lo inet loopback iface eno1 inet manual iface eno3 inet manual iface eno4 inet manual iface eno2 inet manual auto vmbr0...

Hey everyone, after reading a lot and coming to the conclusion... Running a 2 node cluster productively with replicated storage (sync) is not feasible. I have the possibility to build a hardware setup with 3 nodes as follows, whereby these are really the *maximum* possible hardware capacities...

I updated to Proxmox VE 8.2.4 earlier today. I also enabled firewall, which caused access (ssh) to the cluster to go offline. Granted, I was connecting via a VPN server that was running on the cluster. (I'm not sure exactly what the firewall did, I turned it on without any configuration). After...

Hi, i have configured mirroring on a ubiquiti switch to mirror traffic towards the Proxmox server. I can see the traffic from the proxmox cli and now my main goal is to send this traffic towards a dedicated ubuntu vm on which i have installed suricata for network analysis, but i can't find...

Hello All, I am looking for some guidance on the Proxmox environment. My goal is to limit failures outside of the cluster while still allowing other devices on the network to talk to the hosts with HA. I am not worried about the configuration of the switches in the diagram below. I am more...

Hello all, #noob. I am having some distinct network issues and not entire sure how to resolve. 2 main issues are: Multiple network devices have same IP on network despite being configured as different in the GUI and /etc/network/interfaces Unsure of relation to above - Unable to get to...

Server - 2x CPU / 768 GB RAM / 6x 1gbe NICs / 2x 10Gbe NIC's Storage - Very High end flash storage Networking - 2x Switches for "server access" (iLO / iDrac + back end server network) -- we will call this management - 2x Switches for "Trunk Network" (VM's live here) -- we will call this VM...

I am hoping someone can point me in the right direction on how to setup up different networks for the different traffic, including "public" and "cluster". I am new to linux / proxmox, so detailed instructions are appreciated. As of now all 5 servers are running the latest PROXMOX and they are...

Preface: Please know that before creating this post I did my absolute best to not bother you fine folks with this request, scoured the forums, tried some fixes….then tried all the fixes and I am still at the same spot as I started It should also be noted that I BARELY know what I am doing in...

Hi guys, I'm testing proxmox for my work, got it installed and made my first VM. Now I want to get my proxmox server on our local network, on a 10.10.1 subnet in this case. before I just used the standard IP at the setup of proxmox, got it directly connected with a ethernet cable to my laptop...

Hello beautiful community, I have got 5 dedicated IP's that came with my oneprovider's dedicated server. Have tried almost all the methods that I could find over the internet but I am still not able to achieve the results most recently followed this guide...

I have Proxmox setup with a single network card and software bridge. The physical network the host is connected to provides IPv4 via DHCP and IPv6 via SLAAC. I can create VMs with VirtIO NICs and the firewall option disabled, install Linux and everything works (the VM gets IPv4 and IPv6...

Background: I am a relative networking novice and what I have learned has been mostly by accident and preceded the advent of useful AI's so is quite cobbled together. I have somehow managed to set up what I believe to be a relatively secure network and am trying to be prudent about how I add...

My ISP has assigned me a block of ipv6: 2001:19c0:1::1c00/120 I'm currently on Proxmox 7.4. After setting up a new Ubuntu 22 LXC, I've added network settings like so: Static IP: 2001:19c0:1::1c03/120 Gateway: 2001:19c0:1::1c01 I've also tried updating the bridge on the node to include an...

Good evening, I am interested in being able to connect two Proxmox servers to each other and that the VMs of both can be seen no matter where they are. The idea is that they work as if they were connected under the same switch, but the problem is that they are connected P2P. Both nodes are seen...

Hello! I have been trying to setup a server for a student radio at my school. This is my first time working with Proxmox. The reason I choose this software was becuse of the flexibility it creates but right now it's been more of a brick wall that I haven't been able to get past. The current...

What i currently have is 6 node cluster all running on a single 10GB network, What im looking to setup is the same cluster running on three separate physical networks, 1. PVE Management network 2. Application network (VMs) 3. Ceph I'm assuming this is pretty standard but i can't seem to get...

I am new to Proxmox and I'm setting up my first server. So far the only thing I'm confused on is the networking. I currently have a linux bridge (vmbr0) and a linux bond (bond0). Do I need both or can I get away with just having the bond? My host has 4x 1gb nics and I want to bond all four of...

Moin Moin und frohes Neues alle Zusammen! In meiner Proxmox Installation habe ich folgendes Problem: Die Hauptnetzwerkkarte wird nicht richtig erkannt. Früher war es tatsächlichg mal eth0. Jetzt nach zwei neuinstallationen irgendwie nur noch lan0. Auch der Typ wird nicht angezeigt UND im GUI...
