ISA Server (2004) detected routes through adapter "External" that do not correlate with the network element to which this adapter belongs. The address ranges in conflict are: 192.0.0.192-192.0.0.192;. Fix the network element and/or the routing table



Hi,

Just upgraded ISA 2000 to ISA 2004. I exported ISA 2000 settings during the
upgrade process and it reimported them into ISA 2004.

Everything seems to work fine, but I'm getting alerts saying that my network
is configured wrong.

Here is the message:
Event Type: Error
Event Source: Microsoft Firewall
Event Category: None
Event ID: 14147
Date: 18/01/2006
Time: 8:28:02 p.m.
User: N/A
Computer: PCISERVER
Description:
ISA Server detected routes through adapter "External" that do not correlate
with the network element to which this adapter belongs. The address ranges
in conflict are: 192.0.0.192-192.0.0.192;. Fix the network element and/or
the routing table to make these ranges consistent; they should be in both or
in neither. If you recently created a remote site network, check if the
event recurs. If it does not, you may safely ignore this message.

Persistent Routes:
None

In ISA Management - Firewall Policy - Toolbox - Network Objects - Network -
Internal.

It has an IP Address range setup as: 192.0.0.192 - 192.0.0.192.

After installing ISA04 I used the SBS03 Internet Configuration Wizard.

I'm really not that good with working out routing and what I need to change.
Can somebody help me out.

Thanks
Tristan
