IPv6 and ports

[nsordk]

I am very new to Proxmox and struggeling to reach any other port than SSH from outside.

A little information:
Datacenter Firewall active with ACCEPT in inbound traffic
Node Firewall active with ACCEPT in inbound traffic
VM Firewall active with Deny on inbound traffic but macro "Mysql" is created.
VM has an IPv6 address and SSH is working

It seems that connect to port 3306 (mysql) never reaches the VM.

Am I missing something in my setup, or have I misunderstood something.

If the post lacks information, please ask for more, as I am not sure what more to bring to the table.

I was wondering about the firewalld message in the bottom, and I stopped this and now I can connect.

Do I have to use firewalld when I use proxmox firewall?

 

[wolfgang]

No firewalld is not part of Proxmox VE.
do you have installed it on this System?
