networking

Hello, been using proxmox for about a year now and I am trying to improve the security of my cluster. Treating all traffic as a problem until proven otherwise. the Block IPv4 link-local (1000000102) rule on my PFsense firewall keeps blocking traffic from my proxmox VMs coming out of the cluster...

Hello guys, I am currently facing an Issue in our Proxmox Cluster as described in the Title. It does not matter on which Node the VMs are on, or if they run Linux or Windows, it happens on every single one. However LXCs in the same VLAN are not affected, since they dont use the VirtIO Adapter...

I have a server with 2 10G-baset Intel X710 LAN ports and is unable to maintain active connection with the switch. Link go up and down continuously. With the concomitant transition to the enterprise repository and upgrade to version 8.2 the problem has worsened making the server unusable. I...

I figured out my issue before this post could be approved to go public. Wasn't a Proxmox issue, but was a networking issue. Home switch had sticky ports, and each lxc/vm generates their own mac address. Suffice to say, issue is resolved. Not sure if I can delete this thread. If not, maybe...

Hi, I'm hosting Proxmox at Hetzner, which gives me a Proxmox instance behind a public IP. I managed to get proxmox to have an internet connection with the following /etc/network/interfaces config. And vmbr1 and the #nat is my attempt to get it to work for VM's. auto lo iface lo inet loopback...

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...

Hello, i hop you guys can i help me. Currently i have proxmox in the hetzner cloud on a root server. I have 3 Public IP-Adresses. 1. Public IP: 138.XXX.XXX.126 (Proxmox Interface) 2. Public IP: 138.XXX.XXX.96 (pfSense WAN -> LAN) 3. Public IP: 138.XXX.XXX.105 (pfSense WAN -> Mailserver) Hetzner...

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...

Hello, i bought an x86 appliance that have 6 x 2.5 Gb NIC my plan is to virtualize OPNSense as Router and other services ( like HA ) I've installed proxmox and OPNSense with the current configuration NIC0 : Static ip ( used for access proxmox in case of failure ) -> 10.25.25.2 NIC1: OPNSense...

I have installed the whonix gateway as a new VM in proxmox, I was following a YouTube guide but the creator does not seem very responsive. I have Pfsense setup with a WAN 192.168.1 and LAN 10.0.0 which is running fine for my home lab setup, following the Video I have created two VLAN's one for...

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...
