Gordon,

   This should be very simple. In the source select your Internal
Network group,
 then highlight it, right-click and select negate (or negate-cell if NG
is in use).

Met vriendelijke groeten - Bien a vous - Kind regards

Subject: [FW-1] Policy question - FW-1 1.4.2


Hi All,
I am trying to add rules to my policy that will selectively allow  port
80
access to my DMZ servers.
I can specifically code the source addresses for internal clients, but
obviously not for the WWW users.
If I add a line like   -   "any    DMZ   www   accept   fw-cluster"   -
I
immediately make all specific rules for www access redundant !

So I need some way of identifying the Internet users with a global
network
object ?

I could do this if I knew how to code a "negative" rule (ie "if the
source
address is not from my internal network, then it must be the Internet")
but
I can find no way of doing this in the Policy Editor.

Just for the record, this is easier with PIX since the rules are applied
relative to the interface.
I know I can code access-lists in FW-1, but have never tried ; is this a
solution ?

Any suggestions.... please !  (while I still have some hair left )

Thanks in advance,
Gordon
