Blocked by Protocol Analysis (Invalid Flag Combination)

Hello,

I keep receiving, each 3 minutes (±), Blocked by Protocol Analysis (Invalid Flag Combination) messages in my log, like this one:

Description: Blocked by Protocol Analysis (Invalid Flag Combination)
Direction: TCP Incoming
Source: 219.140.14.69:1316
Destination: 192.168.254.1:57319
Reason: ACK RST PSH URG is an invalid TCP flag combination

Many times the source IP is the same, but the Source port is different.
The destination port (57319) is used by Azureus, but the download is ok, and i am receiving green light.
No NAT problems at all.
UPnP is off.

Although, i´m having this problem with others destinations ports too, like this one:

Description: Blocked by Protocol Analysis (Invalid Flag Combination)
Direction: TCP Incoming
Source: 24.80.233.56:54337
Destination: 192.168.254.1:1648
Reason: ACK FIN RST is an invalid TCP flag combination

Does anyone can help me?
Thanks in advance!

Cya!
