Symptom:
ADP and Direction Logging...
Condition:
Every now and then, ADP messages with the following characteristics:
Code:
1 2007-11-13 13:50:53 warn ADP from Any to LAN, [type=Scan-Detection(8122011)]
UDP Port Sweep Action: No Action Severity: medium 10.10.1.16 85.177.205.72 ACCESS
FORWARD
Claims to be Any to LAN (this ADP profile exists) - but we're concerned about source;
destination and the ACCESS FORWARD entry. No firewall rule allows any connection to
10.10.1.16 which is on the LAN!

the action for "TCP filtered port sweep" seems not workable.
