Other modules / Zentyal 6 - HTTPS packets dropped

« on: January 09, 2019, 10:57:18 am »

Hi there,

I have recently upgraded to Zentyal 6.0.  Since then, I noticed that there are lots of packets being dropped (source: internal destination: external port: 443).  I have no rules that should be blocking this set up (in fact I have any/any/any) for Packet Filter>Internal Networks.

I looked up a few of the IP addresses (small sample) and it came up with Microsoft and Facebook as being the destinations.  I'll also note that SmartScreen (Windows 10) no longer works.

So it seems that there are some rules somewhere that are set to drop packets based on some criteria that I have no control over through the GUI.  Does anyone have any suggestions on how I might be able to troubleshoot this?

Edit:  I should mention that I have this running on Citrix XenServer 7.6.  Although I don't think that should matter.

Thanks.
