Hi Rafael,
Have you tried disabling spoof detection yet? Are these real spoof attacks or
is your network configured incorrectly?
Thanks!
Tom

Hi list. I try all sugestions here, but the problem persist. All the time that
it's occurs, the applicatin log regists:
ISA Server detected a spoof attack from Internet Protocol (IP) address
10.11.0.202. 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.
My filter log regists:
2003-09-26 14:07:15 10.11.0.202 200.255.70.26 ICMP 3
1 Spoof 200.255.70.26
This spoof atack can be the reason of my webproxy service crash?
What it means?
Thanks a lot!
Rafael Rodrigues.
