This has nothing to do with your external IP address, it has to do with
your rule and listener. I believe your internal IP can not have two
different rules on the same listener port. So if your exchange is using
192.168.1.10 for OWA (port 80 non-SSL) and you also host a web site at
192.168.1.10 on port 80, ISA won't let you create a rule because it
knows when it gets to 192.168.1.10 the machine on the other won't know
what to do with traffic being past to it.
So you either have to in this case (above) get your machine another LAN
IP, or use host headers for your web site.

Hi Everyone,
A belated Merry Christmas and a Happy New Year to you all...
I am eagerly awaiting the ISA 2004 book... ordered just not arrived down
under yet!.. I have had ISA 2000 operating for some 3 years now...
mostly good... It does all that I have asked of it... I have installed
the first ISA 2004 and have managed to find my way through most of it
however the one thing that I seem to have problems with is OWA using
http as opposed to https. While SSL is more secure I do not have the
resources or (currently at least) the need for that level of security.
However I have been unable to find a paper on OWA http... there is a
excellent one on using SSL... I have had a go at setting OWA http up
using that paper as a guide however I get the following message:
Description: The Web Proxy filter failed to bind its socket to
xxx.xxx.xxx.xxx port 80. This may have been caused by another service
that is already using the same port or by a network adapter that is not
functional. To resolve this issue, restart the Microsoft Firewall
service. The error code specified in the data area of the event
properties indicates the cause of the failure. The failure is due to
error: 0x8007271d
Now I do use the same IP address for the SMTP connector to the mail
server (Exchange 2003) and that is working. Would there be the
possibility that the ISA 2004 is unable to have two services coming in
on the same IP address???? I have 4 IP addresses associated with the
external NIC all other services including VPN etc are working fine.
Any wisdom would be appreciated.
Thank you
