Hello. I am currently in the process of getting Proxmox up and running to host a VM server to replace my ancient Atom based file/plex/deluge/nextcloud server. I have proxmox up and running ok and a few bits and pieces set up on the VM to host my new server, but I'm having a few issues related...

I'm pretty much a noob with ProxMox but if I'm reading these forums correctly, this shouldn't be happening. When I enable the firewall on the data center, I lose the web interface completely (SSH still works so I can disable the FW again). So what gives? I want to use the firewall feature so I...

Hi there, I've been trying and researching this now for a good month and finally need some help. So, I've setup proxmox 6.1 and have 5 VM's, this server will be used in a small office environment. I have VM1 pfSense as firewall/gateway (not working) . VM2 Zentyal as Domain Controller (working)...

Hello, maybe this question has been asked before a lot. I've googled all possible solution to get optimal firewall configuration couldn't find a reference that can help, I don't need tutorials I need conf example file or something to build on. A firewall configuration that: - Give internet...

I'm a little perplexed as to the expected behavior of disabling the firewall for troubleshooting purposes. I've left the default for the datacenter firewall as NO. And for my node the firwall was shown as on in the GUI so I toggled it to NO. Yet, if I reboot Proxmox and check the firewall status...

Hi all! me again. I've been working for around 1 week trying to use Proxmox over ESXi but this is giving me way too many headaches. Still, I think this time the issue is not Proxmox, but my lack of networking knowledge. Anyways, this is what I'd like to archieve: Basically, my server...

Hello all, First time poster here, I've been following Proxmox for a while and now I've set up a VPS in an external provider. My current provider gives me a Supermicro server with only 1 NIC plugged in. I have no control over this as I've already made a ticket to ask my provider to plug another...

Hi, We are configuring firewall for a couple VM's. After enabling the firewall for each VM, it must be rebooted (cold) . We want now to enable the firewall option in hardware>network device for all VM's. And then disable the firewall in Firewall>options enable flag by default. 1. The question...

Hello! I read several times the documentation about the proxmox firewall trying to understand how this is working. But one point remains obscure for me : does the VM firewall inherit from the top level (Node then datacenter)? Thx in advance!

Hello everybody. I'm a bit noob with the topic of networks but what I wanted to do seemed very simple. As the title says I want to block access to the router and the proxmox console among others in an VM. I did not find any information about it on the internet but it occurred to me that the...

Hi guys, I'm trying to setup some firewall rules to protect a VM, but I fail badly and don't have a starting point to find out why. The proxmox host has a public IP X.Y.Z.80 from the network X.Y.Z.64/26 The VM uses a bridged network and also has a public IP X.Y.Z.69 I already tried setting...

Hello everyone, Just curious what others are doing, but is it best to use Proxmox's firewall that is available in the webgui for each VM or use the VM's firewall available within the OS (e.g. ufw, firewalld, etc...)? I'm on Proxmox 5.2-2 and most of my VM's are a Linux distro (Ubuntu, CentOS...

Hello, wanting to configure the proxmox firewall, I find myself no longer have access to the web console and ssh. The server is hosted at Online.net which provides a backup distribution in case of trouble. When I use this backup, I mount my raid1, I get in partition: md126 and md127 According...
