second ssl certificate on isa 2006 and sbs

Hi,
I am running sbs 2003 iis 6 behind a ISA 2006 server and I am now trying to publish a second site through the ISA with a ssl certificate.

I have OWA initially setup and working fine through the ISA with a self signed cert but when I try and add the new additional domain certificate I run into problems with the web listeners saying that they are on the same Ip address and Port.
I have tried changing the ssl port but when I open the url in a browser I still get the original ssl cert for the remote outlook and ISA is blocking the url with 12202 the ISA server denied the specified URL. I have added a second IP address to the iis but I cannot work out how to add this to the ISA to split the two certs/domains.



I am on the right track or can I just add the web listeners to use different certificates for the different domains.

Thanks


Chris

You can specify the certificate that is used on the listener itself.
So when you select the IP address for the listener to use you can also specify the certificate.

Although if both URL's are for the same domain you can avoid any complications by using a wildcard certificate for say *.domainname.com

A second IP address on the IIS will not help. You need a second IP on the ISA box - as that is where the listener resides. Once you have that, the Addresses tab ceases to be greyed out on the listener when you select which network to listen on. That option allows you to select an individual ip address.

Which nic do I need to add the ip address to on the ISA, internal or external?
I have setup the internal network ip as 192.168.16.1 with the iis server/sbs being 192.168.16.2
and the Incoming Ip being 192.168.1.10 with default gateway 192.168.1.1
I only have on Static Ip address coming into the server through our ISP is that a problem?

External.

Yes - you would need a second external (public) ip address.

The EXTERNAL interface needs to have another PUBLIC IP address assigned to it.
And the DNS needs to be configured to use this second IP address.

It is not possible to get additional public IP addresses to this server at this time so have resolved the issue by moving the application to a separate web server that does not have to go through the ISA and is not affected by any other SSL certs on the server.
