I'm very confused what's going on here(19.1.4)

You can see a lot of records similar to the refusal record in the firewall access record.
But the client usually has access to the Internet.
I know there is a problem here, but what puzzles me is that the rule that was rejected has no name, right?
And there is already a rule in this interface that allows access to any rule, why is it still rejected?
What am I missing?
thank you


I don't know what the impact is. :'( :'( :'( :'(

I guess, you did not google for port 7680 that is tried to be accessed.

The issue is Windows Update Delivery Optimization (WUDO). One win10 pc downloads updates for your networks and then tries to deploy them to other win10 pcs in your network (via port 7680).

If you want this, you have to allow port 7680/tcp, else you can disable WUDO like described here:
