Publish multiple web sites over HTTPS on port 443

Hi All,

We have an ISA2006 server in our DMZ which presently publishes Outlook Mobile Access on port 443. This is associated with a certificate for our OMA URL.

I have a requirement to publish another web site from a different internal web server which has it's own certificate but I can not see how to do this on the ISA server as it will not let me configure two rules on the same port even though they have different certificates and desinations.

Both URL's are for the same domain but I already have certificates for the indivdual sites and do not really want to purchase a wildcard certificate. Is there any way I can get both sites securely published.

Thanks in advance.

They don't have two different destinations - they both have the same one - ie the external IP address of the ISA server - unless you have put two different external IP addresses on the ISA external NIC? You can only have ip address/port no. combination. So you either have host headers (2 web sites on the same web server) or 2 ip addresses and DNS A records 9one for each web site) and do it as two rules.

Thanks keith,
If I put a second IP on the ISA server's nic would that then allow me to publish the second web site. I can have the url point to a different external IP (from the one OMA uses) which I could nat to the isa servers second ip address.
