Hi,
I have OPNsense 25.7.8. To keep legacy telephones running, I have a number of GRE tunnels that terminate on devices that are behind OpenVPN on the remote side, and on a system in my internal network. The traffic from the internal network to the OpenVPN link is blocked by the built-in "Default deny / state violation rule":

I have both a bidirectional floating rule without state tracking:

and corresponding directional rules in both the OpenVPN and the internal rule list.
The traffic is still blocked.
How can I get that GRE traffic to pass?
Greetings
Marc
