People, please help.
1. Installed latest Proxmox
2. Firewall works fine for Host
3. Installed Guest Ubuntu Server 16.04
4. For my Guest I enabled Firewall and specified rules:
in DROP
out DROP
but they do not work,
when I login to Guest I can for example > curl google.com
and it works...
I really stuck how to disable ALL in firewall for Guest...
Also my Host /etc/network/interfaces:
Is it possible that Firewall works only for non-Nat cases?
If someone can help - I will create a clean install and let you enter there to check.
Thanks a lot for help!
