Good morning,
are in possession of a Draytek 3200N and yesterday I tried to upgrade the firmware.

I followed the guide Version 1.1:
- I downloaded the firmware "Vigor3200 series" Ver "3.3.7.2" from the site http://www.draytek.com/user/SupportDownloads.php
- I did the update using the application "Firmware Upgrade Utility"
- The Draytek has restarted

Once restarted only worked the lan ... Firewall settings were correct, the DMZ and other settings of central importance to my company did not work.
I also tried to exclude all firewall rules but nothing did not work the same.
I reset the firewall loaded the configuration file and did not work.
At the end I was forced to restore the firmware ver 3.3.7, and returned to normal.


I'm here to ask:
- The firmware "Vigor3200 series" Ver "3.3.7.2" supports Vigor3200N?
- Is there a specific procedure, other than that I followed?
- It 'was changed some settings in the version 3.3.7 and version 3.3.7.2 that I missed?

Thanks
