Thanks for taking the time to get this cleared up.  Your mail from
Checkpoint is greatly appreciated.  It was an intelligent mail and 
deserves an intelligent response.  It also raised some issues 
(thankfully, more on the lines of firewalling technology than spy 
stuff).  FWIW, this will be my last mail on the Mossad issue.

The filters but no proxies issue has nothing to do with it.  The lack of
proxies is a technical area which I think should be addressed in another 
mail thread.

Interesting.  I recently spoke to another Checkpoint employee who claimed 
that the Firewall-1 does have proxies and that the proxies are there because 
some customers required it.  If it's not too much trouble, could you check 
into this & send me an e-mail with the results?

Thanks for the clarification.  As mentioned earlier, I'm dropping this

Well, an employee of the CIA (Pollard?) was caught spying on behalf 
of Israel only 2-3 years ago.  

On a separate, but similar note, Checkpoint has been submitted for 
evaluation to be used in an environment in which it may be connected
to classified networks. (This info is not classified, as it is on an 
Internet web site).  

Please don't be offended at this, but I'm uncomfortable with the 
thought that a product from a nation which was caught spying on 
the USA may potentially be connected to classified networks.  
However, this is an issue for our gov't to deal with - not me, 
and not this list.

I didn't mention the backdoor & won't address it.

Ori, Thanks for the pointer and more importantly, thanks for your
polite response to a sensitive subject.  I appreciate your candor
and the time you put into writing your mail.  Thanks again.

Best Regards,

PS - As far as I am concerned, the threads about the Mossad are dead.
     If someone else wants to continue on with the thread, they will
     do so without my help.
