You only get once certificate per web listener, so if you must have separate domain names as you've indicated, you'll have to get more IP addresses. You could use a single certificate as *.domain.com and make the connections as owa1.domain.com, owa2.domain.com, etc. This would allow you to use a single listener and multiple wpublishing rules to answer this problem.

I have FE/BE Exchange im internal network and publish Exhange on ISA Server 2004 which is on the perimeter network. I have only one IP address for ISA external NIC. I want to publish multiple Maildomains for OWA / OMA / RPC over HTTP and also IMAP4/POP3. I want to use for each publishing the secure publishing with certificates. I tried, for example, OWA publishing for two maildomains: owa.domainA.com owa.domainB.com I defined Web listener on the external IP of ISA with form-based authentication for owa.domainA.com. On this listener, I bound the certificate for domainA and published owa.domainA.com. I tested OWA connections. It worked well. Then I tried to define the second OWA publishing for owa.domainB.com. Because of certificate, I had to define another Web listener and the certificate for domainB. Unfortunately I cannot bind the same IP address for different listeners!!! Is there any solution for it? If not, must I need so many external IP addresses on ISA external NIC like the number of maildomains? Best Regards.
