[SOLVED] PVE, OPNsense and VLAN VM´s

Hello everyone, I’m new to Proxmox and have set up a configuration with a virtualized OPNsense firewall and isolated VMs behind it. Unfortunately, I’m facing an issue where my VMs don’t have a connection to the OPNsense. Can anyone help me with this?

Just to check, these VM's are on the same physical host, correct?
Any reason you went for an ovs-bridge instead of a (default) Linux Bridge?
Do you have any of the ports on the VM's set up with the firewall-option turned on (doubt it is the cause, but just ruling it out)
 
Yes, that's correct, the OPNsens (VM) & VM1 are on the same physical host.

I would like to run several VLANs over a single bridge later, Therefore the OVS bridge.

The Proxmox firewall is active in the VM settings but deactivated in the "Data Center" tab

The pfctl -d command was also executed in the OPNsense to exclude possible rules.

When I try to send a ping from 10.2.0.2 to 10.2.0.1, I only get the message "Destination Host Unreachable".

Here some Config´s:
