Two SSL certs, Two Names, ONE IP.

[LWComputingMVP]

SSL and Public DNS stuff is not a very strong area for me, so I'm looking for help...

Note: the domain names and IPs have been changed.

*Generic Linksys Router capable of handling ONE public IP Address
*Has available up to 5 public IP addresses.
*Client has 2 public domains - "clientdomain.com" and "businessdomain.com"
*Server/Web Server is 2003 Standard/IIS6
*

http://www.businessdomain.com

is a cname resolving to 256.0.94.74
*mail.clientdomain.com is a cname resolving to 256.0.94.74
*PTR lookup for 256.0.94.74 finds mail.clientdomain.com
*Existing MS SSL Cert for OWA is set and

https://mail.clientdomain.com

works fine for OWA
*New GoDaddy SSL Cert for

http://www.businessdomain.com

results in an error regarding reverse lookup failing and if the error is ignored, the OWA site loads, not the

http://www.businessdomain.com

site.

MY QUESTION:
What do I need to do so that BOTH OWA and

http://www.businessdomain.com

work with their own respective SSL certs with NO error messages?

I assume I need another IP mapped to

http://www.businessdomain.com

and that would mean needing to change the router. Correct? Any workarounds or other suggestions?

Are both domain names registered with GoDaddy.com?

Neither are - Godaddy is only used for the SSL Cert.

Host headers will allow for the

http://www.businessdomain.com

site to come up correctly, but the error regarding reverse lookup failure can only be resolved by using a second public IP for

http://www.businessdomain.com

with a router that can support multiple IP addresses. Unfortunately, your generic Linksys router has to be swapped out for one that is more robust.
