Q3. What other Blue Coat servers does the SWG VA communicate with, and why?
A. To prevent licensing issues (duplicate serial numbers), the SWG VA also communicates with https://validation.es.bluecoat.com. Communication attempts to https://validation.es.bluecoat.com occur every hour. The license is suspended after 7 days if no communication can be made to https://validation.es.bluecoat.com. Once communication is restored, the license is un-suspended and the accumulated failure count starts to decrease.
Note: if the VM does not have sufficient dedicated resources, or if the VM is restarted from a snapshot, or if the VM is suspended/restarted, a lost-time-synchronization event may occur. All the lost time will be added to the accumulated failure count.
Q4. Can I deploy the SWG VA in a closed network or in proxy chaining deployment?
A. In a closed network or proxy chaining mode, the SWG VA needs a TCP connection over port 443 either directly or via the upstream proxy on the following hosts:
