If you set up subdomains, can you use a wildcard SSL?
Ex: www.subdomain.domain.com
Do you have to have a separate IP address for each subdomain?

No,

one certificate requires one address and one port.  A wildcard cert is a single cert in this context.

you *do* need to create SSL host headers though, which can't be done using the GUI:

so you don't need different IP addresses for each subdomain?  It doesn't mention that, but it seems I've been told that before.

Re-reading your answer, I'm not sure if you are saying No to being able to use a wildcard certificate with subdomains or No to needing separate IP addresses for each subdomain.

Also, does each subdomains have to be set up to use a different port?

Sorry - this is all new to me-  I'm a simple one web site, one port, one SSL kind of gal.

Hi,

you only need different addresses when there are multiple certificates - i.e. "one certificate per ip address and port combination"

Cheers.
