Using Port 443 on multiple IIS sites through single IP address

Posted on 2012-09-12
Last Modified: 2012-09-12

We have a SOAP/.NET web service that uses 443 and OWA that does not. Looking to implement SSL cert for OWA and would ideally like to use 443 also. I have a draytek vigor in which I have port forwarding for mail and the web service etc - -was not sure if from a single IP address , I can use 443 on 2 IIS sites - or would I need a second static IP? Thank You.

    I think you have 2 options:

    1 - Additional Static IP - this would be easiest for port forwarding.  IP_A:443 -> SOAP:443; IP_b:443 -> OWA:443
    2 - Use a different port external for each - more complicated.  IP_A:443 ->SOAP:443; IP_B:4443 ->OWA:443

    Option 1 would be by far the easiest...

    Thanks, I was thinking that the second static IP might be the cleanest, less hassle way.  I am assuming that if I was to go down the other route, I would need to put the port number into the browser?

    Yes - this could be confusing as some mobile devices must use :443 for OMA to work so therefore you probably couldnt use mobile devices to collect the Exchange mail - this flip-side to that is having people remember to add the port number in theior browser...
