No attached screenshot...
open ISA MMC...
expand access policy,
right click IP Packet filters...
select properties...
on "General" Tab be sure "Enable Packet Filtering" is checked
check enable intrusion detection and IP routing...

Robert,
Please look at the attached screenshot, to me it looks as if packet
filters are enabled. Can you confirm?
Thanks

Robert,
Thanks a lot for response.
I guess, I have packet filters enabled, how do I check that?

Raminder,
ISA only denies all traffic if you enable packet filtering. With packet
filters turned off, all traffic will flow freely through your ISA

Hi all,
As I understand, by default ISA denies all access through the firewall
unless explicitly allowed by a policy rule.
1. Does this apply only to the ISA server or all client workstations
connected to the internal interface?
For me all internal SNAT client workstations are able to access external
applications without any allow rules configured.
2. Could I have done anything during installation for disable the
default "deny all"? (Dedicated Firewall Standalone installation)
I have made no changes after installing ISA, no protocol definitions, no
protocol rules, no packet filters, no site and content rules. I have
just configured a destination set and a client address set.
I would appreciate any help...... I might switch to other firewalls if
this thing doesn't work...though I don't want to.
Thanks a lot
Rami

First, you need to make sure you have your client sets configured
properly
when using SNAT. The client set, and what protocol rules it's assigned
to
will control whether a secure NAT client will be able to get out...
Second, when modifying protocol rules, or protocol definitions, you need
to
stop and restart the firewall service before the changes will take
effect.

Subject: [isalist] SNAT Client
http://www.ISAserver.org
Hi all,
I am unable to stop / restrict traffic using SNAT client.
I have this one workstation sitting behind an ISA server connected to
the
internal interface of the server.
The only connection to the outside world for this client machine is
through
the ISA server.
But still I am unable to restrict and open access to a particular
application on the outside (external network).
I want to be able and give and restrict access to a number of
applications
on the external network at my will.
I have tried protocol definitions and rules, packet filters, but nothing
seems to work.
Client machine can get to the external application all the time. I
cannot
seem to restrict the access.
Please Help.
Thanks
Rami
