I read your doc (http://www.isaserver.org/tutorials/2004wildcardcert.html) and was excited to know that I can publish more then one secure website with ISA with one external IP interface. My question is can I get a wildcard cert from a public cert authority? I had an server ssl (myserver.domain.com) from instantssl.com and they offer a wildcard cert but they say it will not work with ISA and this configuration. They say that each individual cert needs to be bound to an external IP. Am I confused or are they? Any direction/comments would be appreciated. Jerry J
