Port Forwarding Issues
Hello Netgear Community,
My ISP is Cox Communications i have a Netgear C6300BD Modem and ive been trying to setup port forwarding on it but when i do an then go to the website canyouseeme.org it keep saying the ports i want are still closed even though that i port forward them correctly. It is set to DCHP but unfortunatly cox disabled my option to set my ip address to static so i cannot change it on the modem itself.
Note: Routers Firewall feature is turned of and as well my laptops firewall.
Has anyone had similar issues with this cable modem? and if so what did you do to fix it?
Thank You

It's interesting that you believe that you configured port forwarding
"correctly", but it might be more informative to show the actual
port-forwarding rules. Copy+paste is your friend.
Are you running any server program on the target system which is
listening at a forwarded port? "the website canyouseeme.org" is testing
at the router's public address. Have you tried any (local) testing of
the target system at its LAN address? Both should work, and only one
depends on the router's port-forwarding anything.
In my experience, people who talk about ports being closed often
don't understand the problem. A port looks "closed" when there's no
server program listening at that port. All the port forwarding in the
world won't help you if, at the end of the line, no one is listening at
that port number.

"It"? Are you talking about the router's WAN/Internet interface?
The ISP controls that (public) address. Why do you think that you want
to change it?
Why, exactly, are you doing any of this? Is there some actual
problem which you are trying to solve?
