networking

I am curious if there is away to do this without expensive hardware. .. What I am looking to do is separate one particular VM from my Host/VM ip scope. My host and VMs currently using 192.168.0.0/24 but I have a linux vm that is accessible from the outside via SSH and would like to separate it...

My hosting provider is Vultr; I run Proxmox on a dedicated BM server. The host perfectly connects to the internet; however, any VM I create does not connect to the network. Desired outcome: The hypervisor Proxmox has its public IP, then one VM should have its dedicated public IP (the second...

I have a Ark server setup and running in a Windows server VM on my Proxmox machine. I can connect to my server in Ark when I am home and on my local network, but as soon as I try to connect when I'm off my home network I cant join. I've setup the firewall in windows to allow the ports, and...

Hello, I am having a very odd issue with my setup - it is on PVE (7.1-10) running on a Hetzner dedicated box and using vSwitch additional network. Background and setup: I have a Hetzner vSwitch attached to my server. That vSwitch has an additional /28 public network on it. When working with...

Recently hired, I don't think this is a perfect proxmox setup and would like to improve it. Currently, our proxmox cluster has its 3 nodes assigned public IP addresses that we use to connect to them. Fairly randomly, we lose http connection to a node(s) and then just connect to one of the...

Servus zusammen, ich habe bei meinen VM's ein Problem mit der stabilität im ausgehenden Netzwerk Traffic. Solange nur ein VM aktiv ist hält sich der Traffic stabil, in dem Moment in dem aber auf dem Host System gearbeitet wird oder eine zweite VM zugeschaltet wird, bricht der Traffic alle paar...

Hello, I recently updated my Proxmox VE 6 server which led to all my VM losing access to the internet via a bridge made. I googled some fixes and found one which looked promising, it included entering the public IP in I believe the CIDR field of vmbr0; upon doing this it did not fix my issue...

Hello, ProxMox community, The problem I have recently purchased a Converged Network Adapter (NIC) Intel 82576, and I am having problems setting this up. When I start up Proxmox, the computer isn't connecting to the internet. When I am in the BIOS, the NIC lights up as it's receiving data but...

Hallo zusammen, und erstmal Frohes Neues! Ich versuche aktuell auf meinem Server Nat mit einer Zweiten IP einzurichten. Der Server verfügt über eine "Hardware" Netzwerkkarte. Ich würde gerne die IP des Hosts, und die Zusatz IP worüber das NAT funktionieren soll trennen, so das die Container...

Mainly, it would be fantastic if someone could give me a "here be dragons" on using Proxmox SDN with policy-based routing (i.e. multiple gateways with iproute2 tables + `ip rule`). I would like some more advanced networking (e.g. multiple NICs: i have will have 4 very soon). In configuring...

Hi, I am a little bit of a beginner when it comes to the IPv6 protocol and the way Proxmox/linux handles it. For context, we run a mail server on a guest inside a Proxmox box (bare-metal at a web farm). Everything IPv4 is configured and works great. Recently however, a client's MS Exchange box...

I would like to make a router for a 10G+ bandwidth (BGP+QoS+Firewall). Of course I will passthrough the network cards inside to the VM/Container. What is better for that purpose: Container or Virtual machine?

Hello, I can not resolve any hostname on my debian vm as long as ufw is enabled on proxmox. is there some configuration or some rule that I can add? I'm running proxmox on a dedicated server, the installation was made with the hoster's iso. it originally came with following networking: auto...

Greetings, We're running ProxMox 7.1-5 on Dell R7525 servers (AMD cpu) with (2) Dell Broadcom 57414 Dual Port 25GbE SFP+ nic cards attached. We've got (2) 25GbE switches cabled correctly and connected to our ISCSI storage appliance. One card is in Riser 1 and the other is in Riser 3; I'll...

Greetings. I just installed an Intel X520 to a 10gbe/2.5gbe switch and I'm still limited to 1gbe on my VM (OMV). I used ethtool to check the physical links and both my bridge and my physical are 10gbe on my hypervisor (Proxmox). Bridge: Settings for vmbr10: Supported ports: [...

Hey all, Simple question: Is there a way to see a local PBS instance [Public] IP from a remote? local (off-site) <-- Pulls from <-- remote (on-site) In short, I know the on-site (remote) PBS IP, but not the off-site (local) PBS IP. Checking /var/log/auth.log, /var/log/wtmp.log...

Hi all, I followed the guide on upgrading from Proxmox 6 to 7: https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0 The host I have done it on is a test server before I roll the update out to production servers and after running the upgrade I have no networking. I have seen a number of users...

HI, I'm struggling to get my head around H/A with OVH and vRack. I have a small database server I want to provide some redundancy too. I have three servers located in the same region and vRack configured with a subnet of IPs. Can someone give me an example of the networking? I was thinking I...

Hi Everyone, My local Proxmox Backup Server stopped networking for some reason (possibly a driver issue?) while running as a VM under BHyve, so I issued a systemctl restart networking and things returned to normal. However, the Proxmox Virtual Environment cluster now shows the PBS repository as...

I would like to ask for a new feature: Service IP for a PVE cluster. I.e. the Proxmox cluster manager should be able to configure an IP address that is always active on one of the nodes (maybe the cluster leader). This would make it easier for automated tools to talk to the API. In case of a...
