All the ports are closed

Sat Jun 23, 2018 8:21 pm

I run this: http://www.yougetsignal.com/tools/open-ports/
All the ports are closed in the centurylink C1100T modem/router. Is that why I
can not connect to any device in the network from the net please? I believe that
port forwarding set is ok. I am benyrey.dyndns.org?

May be there is a firewall blocking the ports.

Thanks

Beny

The port(s) need to be open in the device that the router is forwarding them to. If not, the tool will report them as closed.

All the ports are closed in the centurylink C1100T modem/router.
If your using a Centurylink supplied and configured router, you may want to contact their customer service people. They have their own network security policies.
