Cant get access to some servers i have (fligtradarfeeder, mc server etc on public ip 100.70.42.*) after trying for hours. NOTE: iprange 100*.*.* and NOT internal 10.*.*.* 

Tried with my ISP dns server and with 1.1.1.1, 9.9.9.9, 8.8.4.4 , 8.8.8.8 but hostname will never resolve.

Just went from a Asus meshsystem where *.asuscomm.com worked flawlessly and to make matters worse i cant even connect via ip and port when on a different network. Portforwarding is set with both public port and with internal port. Ip and port works fine when connecting from the local network. 

What am i doing wrong or will i have to return this despite the good reviews?!
