Some versions of personal firewalls can give false alerts when streaming media content is delivered to your computer.

These alerts are not indications of hacks, the packets that cause these alerts are typical for network traffic from such streaming servers.

They are, in fact, IP Fragment Overlaps but can be sensed as UDP port probes.

Some firewall vendors offer help and solutions for this issue, please contact your vendor for support.

If you believe that your firewall is not triggering false alerts, then please forward the following information to [email protected]

The alert date, time and time zone.
Your firewall software and version number.
Your operating system.
Your internet connection speed.
The type of alert, as reported by your firewall.
The port number(s) the alert triggered on.
The protocol the alert triggered on (TCP/UDP/ICMP)
Source and destination IP address
If possible, a sample packet log.

Thank you
