Hi , i experience time to time when i used the the dns resolver from the router in nat mode they stop resolving after a sometime a couple hours or couple of days. I have to reboot the router to get back dns. So now i use my upstream dns server and all work...
To analyse this issue , please send the below information to this email id (email@example.com).

We have also experienced this same issue as well.
We now make it a point to use multiple DNS servers and that has remediated the issue. I've posted a topic about this as well in that the DNS does not appear to relinquish DNS1 from the LAN gateway of the cnPilot itself.
