unexpected data in protocol detection

Hello,
I'm just curious what does this "detection" mean. I got tons of them. Wondering if it's another bug or maybe it's just me. But still, what's this?

Detected unexpected data in protocol UDP ​

No clue why or when this happens so, can't really tell you much more information. Just curious cause I got so many.

What is your network configuration?

Modem? Wireless? Cable?

Are you behind a Router? Wireless? Cable?

A quick answer: The data within the UDP packet is unexpected.

A longer answer:

When the firewall intercepts an inbound UDP packet then various checks are made, one of the checks is for packet content. For example. When an inbound UDP packet with remote port 53 is intercepted, it is expected to be a DNS reply, so the content of the packet must conform to the protocol, if not, then the packet will be dropped with a "Detected unexpected data in protocol" log entry.

In your case it is not possible to say exactly what is being dropped, unless a capture of the dropped packets can be made.

That would be cable.

Ah, thanks for the "unoffical" awnser.
