You may be blocking it in the content filter by name - which has no effect if the web 
page is pointing you at it numerically. you may want to add that numberic IP to the 
content filter. Or better yet block the whole range at your router level.

That is of course, if you don't like advertising. :)

I get these also. this is ad.doubleclick.net - you'll find them from a
variety of other websites.

What happens is you connect to a website which connects you to the ad
server - during the time that you are connected there the sonicwall
'times out' your connection, and the ad server tries to continue
communicating with you - thus triggering an event.

Since this particular one is an ad server, you might consider blocking
it.

Subject: [SonicWALL]- TCP FIN Scans?


Recently I have been receiving multiple TCP FIN scans per day coming
from a specific address.  Listed below is an excerpt from our SonicWALL:

Probable TCP FIN scan -         Source:216.73.82.11, 80

The destination of course is that of our SonicWALL's public IP address.

Anyone know how to stop this?  I get about 6-7 emails per day (during
business hours only), all identical from the same IP address listed
above.  Any help would really be appreciated.  Thanks.
