We have a static IP through CenturyLink and are connecting to the internet just fine with our Actiontec GT784WN. We have installed a device that needs port forwarding.
I've gone to the Advanced Setup and added all the ports to forward to the LAN IP address of the device.
When checking with an open port scanner, I get the following results:
443 - filtered 1433-1434 - filtered 7100-7130 - closed
I'm not sure if I need to disable NAT, enable DMZ, or something else. Any help is appreciated!
