RRAS and 2 public IP addresses

Hi,

we have a 2008 server with 2 public ip addresses. We want to use RRAS with SSTP protocol with one of the public ip addresses. So, port 443 is in use with one public ip address.

We want to use the other public ip address also with port 443 for a special web server.

But the RRAS takes all of the public ip addresses automatically. How can we limit RRAS to only one?

Regards,
Hans-Peter
