RT-N66U Port forward lost ?

Hello,

My port forward rules are not sticking after ipchange and my adress(ip) became "pingable from internet" on without me doing nothing. (the option is off for sure)

I cannot connect to my 2 machines at my home. My DDNS is working. (my new ip was reported)

Something happened.

Any help ?

I'm almost sure that a restart will help but i just don't want to make it a "common practice".
