V19.0 GA Thread: https://community.sophos.com/sophos-xg-firewall/f/discussions/134009/sophos-firewall-v19-0-ga-feedback-and-experiences
Thanks to the development for two features (only from the first things I read there):
-Opt-Out of Assistant
-fixed IP for at least SSLVPN
For us the PPPoE Bugfix is missing but we knew that. So I hope the development can bring this one into MR1 manually again so that we can use the features mentioned above. Keep working on this way (to implement/fix annoying things or long desired features) your customers will appreciate it...
Which PPPoE Bug do you refer to?
Have a look into 05251465. There was a problem with PPPoE automatic reconnect.
