Hi,
I have Symantec 14.0.3929.1200 running on a Windows 2012 server with mainly Windows 10 clients running the same version of Symantec.
Many times a day during normal usage, the client machines get a pop up saying that a specific IP was blocked. These IPs are all owned by Google and are for their services that a computer's Chrome browser is using (such as Hangouts, Drive, Gmail, etc.). When this happens, the user cannot access the specific Google service for 600 seconds. This only seems to happen a few times a day. For most of the day, the computers have no problem accessing & using Google services.
I know that I can change the time that Symantec blocks IPs, but I don't want to make it shorter than 600 seconds in case there is another intrusion that is actually a threat.
Under Policies - Intrusion Prevention - Excluded Hosts, I've added several Google IPs (173.194.205.189, 173.134.204.189, 172.217.10.227, 172.217.11.14, 209.85.232.189, etc.), but I feel that no matter how many IPs I exclude, a new Google IP will be blocked. Is there a fix for this or did I miss something when during setup for Symantec to allow Google services/IPs.
Any help/ideas would be appreciated.
Thank you!
