We have an ISA 2006 server sitting in our DMZ, we have a MOSS 2k7 server, a IIS 6.0 server and IIS 7.0 server we have two internet domain names xxx.com.au xxxx.com.au. These websites are served from our iis 7.0 box. however there are a number of A records for these two I.e. xx.xxx.com.au xy.xxx.com.au xx.xxxx.com.au and xy.xxxx.com.au these are used in web publishing rules for various web applications from different servers. I.e. Hot Docs / Bugzilla/ among others.
Now for my question: the ISA server is used for all of these, can I secure external traffic whilst keeping http for internal utilising one ssl certificate, my boss wants this because he doesnt want to purchase numerous Verisign Certs to achieve this.(We have to use Verisign for political reasons.)
My thougts are that even if verisign offered a wildcard certificate which it appears they dont, the multiple .com.au's would mean at least two certs would be required.
Please let me know your thoughts.
