URL Alias WildCard for Windows Updates

[CuninganReset]

Hello.

I only want to allow the access to windows update servers, but the issue is that the list of URLs that microsoft is providing has Wildcards like:

http://*.windowsupdate.microsoft.com

And when i put that into the Alias the line dissapear.

Do you know any way to make this?? any of you are filtering all but windows updates??

Can't be done. There is no way to obtain a list of IP addresses for a wildcard domain. You would have to resolve every possible hostname which would be infeasible if not impossible.

One of the other packages, such as pfblockerng might have a pre-compiled list you can use. Not sure.
