This is possible now. The primary source of information is found here: https://developers.google.com/maps/documentation/business/articles/prelaunch_checklist#firewall
Configure Firewall to Allow Access to the Google Maps API Services
Why it's important: The Maps API services use a variety of domains, some which do not belong to the *google.com domain. If you are behind a restrictive firewall, it is important you understand which Maps API services use which domains.
Failure to allow access to the correct domains will cause API requests to fail, which can break your applications. For a complete listing of domains used by the Maps APIs, please consult our portal resource (login required):
Log in to the Google Enterprise Support Portal The support portal is only available to Google Maps API for Work users. Navigate to the "Resources" tab Select the Resource called "List of domains used by the Google Maps API Family." You should allow your applications to access these domains.
Please note that we do not recommend managing firewall restrictions by IP address, as the IPs associated with these domains are not static.
