Secondary IP and SSL - 28.May2008 3:57:58 AM

I'm hoping someone can give me a bit of guidance and advise. I am running ISA 2004 Standard with two nics (int and ext).
I want to publish 2 secure websites. I have one working (OWA) but have discovered you cannot have a second secure site on the one external ip.
My options are either
1. purchase a wildcard domain ssl certificate which I believe will allow me to publish these two sites via the one ip
2. add a second external ip address (we have 5 available) and publish this site on the second ip
My questions are,
which is the best option and if I go for option 2, what are the steps involved with adding the second ip.
Is there another option.

Thanks in advance

Purchasing a Wildcard cert will allow you to publish two sites using one IP and web listener but there are limitations with ISA 2004 in doing so. The articles below should be of some explaining the limitations.
One option you may want to consider is upgrading to ISA 2006.

Thanks RB

They were good articles to read, especially the one on publishing multiple sites.We are reviewing a couple of options at the moment and these articles have helped as part of the research/review process.

Thanks again
