Hi all,

I think I know the answer but thought I'd ask anyway, as someone might have some suggestions.

So in IIS we can have multiple websites bound to the same IP - this is called "Hostname binding", and means that IIS will check the Host header of incoming traffic before deciding on what to serve.

Can we do anything similar in TMG?

Or, if I want to handle requests for the same port (443) for multiple applications, do I simply need to get another IP address an interface onto the TMG box?

Thanks in advance.

Hi,

When you publish multiple Web sites with different host names on the same Web server, you can install a wildcard certificate on the Web server that can be used to prove the identity of the Web server to the Forefront TMG computer. A SAN certificate can also be used.

There is a article describing how  to configure Web publishing rules in Microsoft Internet Security and Acceleration  2004 (ISA 2004) Server or Microsoft Forefront Threat Management Gateway, Medium Business Edition to redirect HTTP requests from the Internet to a specific internal Web server by using the original host header.
