ISA Server on SBS 2003

Hi,

I am new to ISA server. Can anyone please help. I have an ISDN dial-up setup
from the server to the ISP. The network uses this for browsing and e-mails.
I have setup a monitoring report that is e-mailed to me. It comes back every
day with this message.
Critical Errors in Application Log

ISA Server detected routes through adapter Server Local Area Connection that
do not correlate with the network element to which this adapter belongs. For
best practice, the address range of an ISA Server network should match the
address ranges routable through the associated network adapter as defined in
the routing table. Otherwise valid packets may be dropped as spoofed. (This
alert may occur momentarily when you create a remote site network. You may
safely ignore this message if it does not reoccur.) The address ranges in
conflict are:
0.0.0.1-126.255.255.255;128.0.0.0-155.239.143.85;155.239.143.87-155.239.143.253;155.239.143.255-155.239.255.254;155.240.0.0-192.168.9.255;192.168.11.0-223.255.255.255;240.0.0.0-255.255.255.254;.

information, see the Event log.

The IP address range 155.*.*.* is the IP address of the Server on the
Internet via the ISDN. How do I setup ISA server to ignore these addresses ?
Sorry I am so ignorant, I just can't seem to get it right.

Kind Regards
Kev
