That makes no sense to me.  You would use a firewall to permit or deny 
ipsec packets right?  So are you saying that if you attempt to permit 
ipsec through a M$ firewalled box, it creates a vulnerability?

IPSEC was not intended to be a firewall, but a secure way to pass data 
across an public network.

What am I missing?

&gt; Geesh, they can't even get packet filtering right!

Agreed, but I'm still trying to make sense of of the 'IPSEC is not 
intended to be a firewall' statement.
