firewall

Hi, I'm new, but I thoroughly go through dozens and dozens of threads already on the proxmox forum. I know I know it is a subject which has been asked before many times but without a very good answer. 1/So I've tried to block the 111 and the 2049 ports on each of my node on the pve part of...

Hello, can someone help me with port forwarding in Proxmox VE 8.0.3? I want to configure access using my public IP address so that I can still access the virtual environment when I'm outside my network. I have set up port forwarding in my router (see images), but when I try to access it from...

Hi, I want to use the Proxmox VE firewall to prevent my VMs on the NAT network (vmbr1) from accessing my local network. My first thought was to use the firewall, but after enabling it, my NAT setup collapsed. I'm pretty sure I did something wrong, but I just can't see it.... I'm not a networking...

Hello, I am trying to access the Ubuntu VM from my Mac using the AFP protocol. If I switch off the VM's firewall, this also works. However, it does not work when I switch it on - although I have enabled the corresponding port 548 (https://support.apple.com/de-de/HT202944). I currently have the...

Hello, I've a container which needs to send mails to a server located in the internet via SMTP. Default outgoing behaviour is reject. I started with an outgoing rule using the SMTPS-Macro and restricted the destination ip address. So far, so good; but it didn't work. So I removed the IP address...

Hello guys, I started to install a Proxmox VE on a server as a Home Lab to host some services. Those services needs to be accessed from anywhere. Basically, I've followed this tutorial: https://blog.zwindler.fr/2020/03/02/deploiement-de-proxmox-ve-6-pfsense-sur-un-serveur-dedie/ But I think...

Hi there! I'm running into a really wild issue here: I want to access my PVE remotely from a different network, so I'm using a wireguard VPN running in an LXC on my Proxmox node. I can use it and ssh into it and other LXCs just fine, however I can't access the pve itself neither by ssh nor by...

Proxmox 8.1.3 - So we have a firewall at the Datacenter, Node and VM level. I want to add a rule so that all VMs cannot access a computer (not on Proxmox) on a specific IP addresses. Do I need to add the DROP rule on each VM or can I put one DROP rule at the Node level? On a firewall rule, if I...

Hey everyone! Quick question: Does the HTTPS macro of the PVE Firewall include UDP traffic (to port 443) or is it still just TCP? I am on PVE 7.4-17, but if it is available in PVE 8.x I would also be interested in the answer, since I plan on migrate to it soon. Thanks in advance.

Hi All, I would like to implement the following. I've been fighting the whole weekend to set this up, with no success so far. Initially, I wanted to use Sophos XG as my Firewall, but I reverted back to Pfsense for now as it seems easier to configure for a noob like me. On my...
