[SOLVED] Proxmox 9, Firewall config logic after update

[aballi1]

Hi,

i have different servers with proxmox 8 and 9 running.
I currently prepare the migration from 8 to 9 with also a new set of hardware, so i installed proxmox 9 freshly on bare metal servers.

i copied my firewall config, which i used since proxmox 6 (not copy, but adding via GUI)

Looks like sth. changed between 8 and 9

This is my "Datacenter" config:



The Security Group "general" has the following config:



i know, some duplicates, but this was due to testing, why the settings are not working.

Input/Output/Forward policy is set to "allowed", and then on each level the last setting is "Drop" as you can see.

Problem:

When i activate the Firewall on Datacenter level, the rules for Port 2222 and 51820 for example are not working, but they did in proxmox 8
i added the same config on Server level, still no access to this ports. The Access to SSH (22) and PMG (8006) are working, just the last 2 doe

It works on my machine. How did you test this? Are you sure your source port is also 2222 and 5180?

sorry, you're totally right and i was blind. The Source port was not necessary, only destination port.

i did this setup already more than 20 times. first time i had issues with that. Sorry again.
