Re: PIX 520 log file

Hi,

NETBIOS Name Service packets (UDP port 137) are arriving at your outside interface, coming from 65.203.82.28 and 65.203.82.29, and destined for 208.178.91.68. This kind of traffic is denied by the Adaptive Security Algorithm (ASA) if no access-list is in place explicitly allowing this kind of traffic.

Kind Regards,

Tom
