[SOLVED] No connection between host and guest!

Hi there.
I have a server with only one physical NIC.
This NIC is the Internet Link to the server itself.
Works fine in the Proxmox server!
However, I have had created a separated bridge NIC, vmbr1 and there is no physical NIC attached to it.
I have had created a couple of rules to do NAT (MASQUERADE) to provide internet to the single Linux Debian VM installed.
This VM had one NIC, attached to the vmbr1, the fake bridge.
Inside Proxmox host, I can't ping and do ssh access to the VM which is using the vmbr1, unless I deactivated the firewall in the Network configuration.
I alread have had put some rules to tried open ICMP or SSH connection and nothing.
What's I doing wrong, please!
