ISA 2006 SSL

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.

Regards,

Carl

Oops... Missed that one Verisign do wildcard ssl certs, however much of the question remains valid, can you secure communication externally from an ISA box with one generic certificate?

This is possible with ISA with one certificate. The verisign product you are looking for is called a SAN SSL. Subject Alternative Name SSL http://www.verisign.com/ssl/buy-ssl-certificates/subject-alternative-name-certificates/
You would use this SSL to publish your sites through ISA as normal. There are many guides out there to help you set this up and the ISA wizard is pretty self explanatory.
