How are you, I would like to ask about this kind of problem. I'm using Shibby Tomato Firmware 1.28.0000 MIPSR2-131 K26 USB AIO
and I have this problem since I flash my Asus RT-N16. I was noticed every time my router restarted
or after its rebooted due to power down DDNS is never came back until I "Force update" it. When I tick force update and click save, then the status is changed and it works afterwards.
I have no issue using my DD-WRT router, when I restart it within few minutes it will works and I can access my router from internet.
sorry I cannot post the picture, seems I'm not allowed to do so.
I'm pretty new on this firmware :D… is there any other solution that will works on my case? thanks a lot for the advise and suggestion..
