networking

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...

Guten Abend alle zusammen, ich habe seit ein paar Tagen mit Mac Abuse Meldungen von Hetzner zu kämpfen. Komischerweise sind die Unerlaubten Mac Adressen die Hetzner mir in der Mail zugesendet hat, Mac Adressen die automatisch durch die OPnsense erstellt werden. (siehe Bild) Wisst ihr ob man das...

I mounted my synology nas via iSCSI and created a LVM on it and made it avaiable to my 3 nodes. One of those nodes is unused and is just there for quorum. On that node that runs no VMs I see really high transfer from my NAS to that proxmox instance (45MB/s continuously). Even after I remove...

Here's what I have: Proxmox installed on a very powerful machine (RAM/CPU-wise). I have granted generous amount of CPU + RAM to pfSense guest. Now I have a 10gb uplink 9000 MTU connection for WAN. It's fiber / SFP+. I am doing full PCIe passthrough. (all functions of card selected, PCIe...

Hi, so due to security policies of my company, I am in need of a double bastion networking setup to connect to my VMs in Proxmox. If I were to ssh into one of my VMs the steps would be: my_pc -> ssh jump_server -> ssh pve-node -> VM However, using Terraform with proxmox provider, I am able to...

Hi, We installed proxmox for our client, but lately we got this error message in the log file warning : enp0s31f6: post-up cmd 'echo 1 > /proc/sys/net/ipv4/enp0s31f6/proxy_arp' failed : returned 2 (/bin/sh : 1: cannot create /proc/sys/net/ipv4/enp0s31f6/proxy_arp : directory nonexistant)...

Hello guys, I'm pretty new to Proxmox and virtualization/networking in general and I've searched for this topic quite a bit. So basically my problem is that I have a dedicated server on Hetzner with the IP (65.21.121.xxx) and I got a subnet package from them for me to assign an...
