Release Post: Sophos Firewall OS v19.0 MR2 is Now Available
Old v19.0 MR1 thread: Sophos Firewall: v19.0 MR1: Feedback and experiences
Keep in Mind: V19.5 GA cannot be "downgraded to V19.0 MR2".
Upgraded vom V19MR1 to V19MR2 and all https/ssl traffic was blocked due to Application Control.
SSL/TLS decryption on Port 80 and 443 is activated.
We were using a customized App definition filter which is not longer working.
Then we tried to use the pre defined filter "Block very high Risk (Risk Level5) but traffic was also blocked.
After using the pre defined filter "Block filter avoidance apps" the traffic was passed.
I'd like to investigate, please see DM.
Issue is confirmed, related to Sophos Central pushing templated Application Filter Policy to firewall groups. Not related to 19.0 MR2.
