Doing this simply requires that you set up two virtual servers on the CAS server. One services on one IP address and the other services the remaining web services on using a different IP address.;

Note: Each virtual site setup will need its own IP address.

Here are the steps:

1. Obtain a separate certificate for and
2. Create a new virtual server in IIS on the CAS.
3. Create a new Autodiscover virtual directory in the new virtual server and remove the old one.
4. Assign separate IP address, and certificates to each Virtual server.
5. Configure your internal SCP to point to
6. Configure your Internal and External Service URLs to point to
7. Make sure that your configured URLs will resolve internally and externally via DNS to the expected IP address for each of the services.
