I have a website in IIS and two different IP addresses on that server. I want to be able to assign a separate SSL certificate to the same site on IIS with the other IP address.

Something like this:

www.abc.com --> 1.1.1.1 --> SSL cert for ABC corp --> WebsiteX

www.xyz.com --> 1.1.1.2 --> SSL cert for XYZ corp --> WebsiteX

I've been fighting with this for a while now and it seems like WebsiteX can only have one SSL cert assigned to it. Is it possible to do what I'm proposing in IIS 7.5 or will I have to make another site in IIS for this?

You need to have two separate bindings, one for each IP address. Each binding can have an independent certificate assigned.

Two bindings can exist on a single site definition in IIS.

That being said a SAN / UCC certificate will likely be the easier route to go.

That will only require one IP address and binding.

You'll need a SAN (Subject Alternative Name) certificate (also known as UCC) with both site names on it. Then bind that cert to the single site in IIS.

  • No. For SAN EV certificate, only one name is displayed on "the green bar" of a browser. Browser would display green "XYZ" on the site www.abc.com.

  • Good point, I missed that this was for an EV cert.
