Hi all,

Is there a way to block clients access the Firewall Client?

I have a LAN that, when any workstation starts, the client firewall installed stop the service Firewall in my Isa Server.

Thanks

Hi Elizabeth,

The Firewall clients are shutting down your ISA Server? I've never seen such a thing!

Thanks!
Tom

Hi,

No. My cpu goes to 100% and the service wspsrv goes to 500MB. In Event Viewer appear the message:
"ISA Server detected a spoof attack from Internet Protocol (IP) address 10.x.x.x. A spoof attack occurs when an IP address that is not reachable via the interface on which the packet was received. If logging for dropped packets is set, you can view details in the packet filter log."
In the firewall client icon appear a red exclamation.

Thanks

Hi Elizabeth,

Is the LAT configured correctly?

Is the external interface on the same segment as the internal network clients?

Thanks!
Tom
