Re: Firewall client not working but its session is visible in ISA-

You can't use the Firewall Client on a single homed ISA.

Things may seem to be working when "nothing changed on the ISA" because
things are messed up to the point that the Clients are not trying to use the
proxy and are going direct,...which the "firewall appliance" is perfectly
happy to do if you never configured it to only allow outbound HTTP/HTTPS
from the ISA's IP# only.

Hi Jim,

The Isa server is installed on a unihomed computer. The server has a
single
nic connected to our lan. It is not installed as a firewall because we
use
our own firewall appliance. The isa server only filers internet traffic
and
sends it to the firewall. Anyway the problem seems to have gone, out of
the
blue the fw-client worked again. I'm wondering if we could have switching
problems in our network, becauses nothing changed in the Isa
configuration.

Kind regards,
Boein

sounds.
is this ISA deployed on a single- or multi-homed machine?

Hi all,
I'm running ISA Server 2006 on windows 2003 R2 and configured it to work
as
a proxy-server. When the clients connect via the browser there's no
problem.
When the clients connect via the firewall-client with proxysettings
disabled
in the ie-browser, the client cannot surf. Although, when I look in the
active sessions on the ISA-server, the client is listed there and it's
session type is "Firewall client" . I enabled firewall client support on
the
network, but are there other things I should configure to make this work?

Thanks
Boein
