Description: Description:
The ISA Server services cannot create a packet filter 170.xxx.xxx.xxx.
This event occurs when there is a conflict between the Local Address
Table (LAT) configuration and the Windows 2000 routing table. Check
the routing table and the LAT to find the source of the conflict.

As per Microsoft: "This behavior occurs because when the ISA Web
service listens on the external IP address on behalf of the Web
server, and the internal client tries to access that service, Web
proxy tries to create a packet filter for that address because the
proxy views that the address as external (which it is). The packet
filter driver fails to create the filter because the address is not
reachable through the external interface; instead, the address is
reachable through the loopback interface. The result is the event log
entry. " See the link below for more information and workaround.

I believe this is the problem I am having. But the forum I was
reading did not include the "more information below" to help me
resolve this issue. Any ideas?

We are running ISA management 2000 on a 2000 server. I have created
static routes to a given external IP. The local PC's are able to
reach this destination but when I look in the event log it is filled
with entries saying "cannot create a packet filter
170.xxx.xxx.xxx" (this is the IP address of my static route). I am
hoping someone has some thoughts on this matter. Thanks
