Hi!
We run about 600 bridged SPA122s on version 1.3.3 for quite a while now.
I upgraded 50 of them to 1.3.5 XU to test it and I was glad I didn't upgraded all 600 of them.
It randomly disabled the bridge functionality on half of them.
The option was still set to 'Bridge' but no packets were allowed through it.
The result was 25 clients with a phone line without Internet access.
I then tried to downgrade one of them to 1.3.3 but it had no effect: still no bridge.
We found a 'solution' and it was to log in to each ATA and put them into NAT mode, then but them back into Bridge mode.
I suspect an internal script is run when switching mode and it was not executed during the upgrade.
You can understand I am not going to upgrade our remaining SPA122 until this issue is fixed.
I can provide configurations if needed.
Thank you !
Julien Berthelot
