strange logs -- tcp port 16166

["Jiang Peng" <pengf () hotmail com>]

Hi all,

For the last month, I received the following log message continuelly =
from the PIX firewall:

 %PIX-4-106023: Deny tcp src outside:87.104.162.116/64604 dst =
inside:hostname/16166 by access-group "out
side_access_in"

At first, there were only a couple of messages every day, but from last =
week, there are 30-40 messages every day.
All the message has the same source, source port and same destination, =
destination port. The destination is our external DNS server. I checked =
google, but still no idea what kind of services running on port 16166.

Does anyone have any clues for this message?

Thanks,
Jiang
