Model: Archer C3150  
Hardware Version: V1
Firmware Version: Latest

I'm trying to get port forwarding working on my C3150, I've successfully forwarded the ports and reserved a static local IP for the machine the server is running on. I'm also able to connect to the server on the same network using private IP, but not able to connect to it from outside the network or internally by using the public IP (hairpinning issue.) My modem is a Netgear CM700, so it's not a bridging issue. I'm stumped on what the issue is, any ideas? Here are the virtual server settings:

 

Could this be ISP related and how could I confirm?

Edit:
I've also included the system routing table, in case that's helpful. The inked out parts are identical and similar to my public IP, though the last digits are different.

@Tony Found out the issue, it was application/server specific. The game server I was trying to run claimed you only needed ports 2456-2458 open. Many more ports needed to be open for people to connect.

@MySeacat 

 

Try setting the server as the DMZ to see if it could be firewall-related in the TP-Link router (disable the DMZ after testing). If that does not work it could possibly be ISP? If any, maybe reach out and mention if ports are being filtered.

 

Another thing you could try is to make port forwarding rules for a single port rather than a range.

 

Also, try to change the port your server uses to something else like 8000, 8001, 8002. Then create the port forwarding rules to reflect that.

@Tony 

Enabled DMZ for host system, was able to have someone connect from outside network. I tried making a single port rule, as well as changing the ports, no dice.
Thoughts?
