In our network environment, Internet traffic runs through a web filtering firewall and access out to the web is very limited.  From what I understand about Solidworks installation, the computer will have to go out to the Internet at some point in the process for license verification, and possibly updates.  Does anyone know the URL that the computer tries to go out to for this step? 

What URL do I need to punch a hole in the firewall for, so that Solidworks can be installed?

Is there a different URL that needs to be allowed afterwards so that Solidworks can do periodic license and update checks?
