Block access to manager router

[redxlus]

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 access to the router is by browser the same as proxmox, so if I block the access with the firewall it should not allow access.

I have not succeeded. I leave the captures here.

did you also activate the firewall on the nic of the vm? hardware->nic-> check firewall
(and possibly also on the datacenter level)

Yes, I had forgotten to activate it in the data center. My fault!
But another flaw was that it had to be OUT not IN
but it works perfectly. Thank you!

Now I have another small problem, I had another machine with OpenVpn and even if I have disabled the firewall on that machine it does not work. It is a machine with ubuntu no container.
Do I have to create a rule at the data center level?
I already have the ports open in the router. UDP 1194. But I do not know what the norm would be like in the proxmox firewall interface
