Just tried the latest version back to 1.0.9.1 which works fine. Got to admit I didn't do the reset and then load the files back on as I don't think it would make any difference.

Up and running


Okay reset the router to defaults
then flashed the firmware
rebooted and reloaded the original config
rebooted
No udp access to camera's and then after five minutes they came back up. Earlier versions of the firmware didn't have this slow response.

I can confirm an identical problem on 3900 too.

On this model the existing port forwarding rules don't work, and new ones won't enable. I tick the box, press Ok. It says the update was successful but the rule stays disabled.

I uploaded my 2960 with latest firmware 1.1.02 .
My NAT port redirects are now not working.

Where do I get the older software from to back this out?

Try ftp.draytek.com

My is working fine now but you have to set it too defaults after flashing and then reload your configuration.
Don't ask we why that fixes it but it does.
