Port foward is blocked by an automatic rule. Which, and how to fix it?

[rasved]

Hi.
I'm running a minecraft server local at our network.
When I want to expose it for external users, I have set up a port forward following different guides. They seems logic and correct, but I still can't get through to the server.
When I observe the live log, I see, that the request is blocked by an automatic rule. Please see screen shot from Live log.

I believe the port forward is set up correctly, but:

* What is "rulenr"? Is it short for rule number?
* How do I see the rule numbers (if such exists)?
* What am I missing, since the request from open internet doesn't come through?
* How can I fix the rule (rulenr 10(?)) to NOT block requests from the open internet to my minecraft server?

Thanks in advance.
