CAX80 Port forwarding broke
Recently I discovered that I cannot setup any port forwarding on my CAX80. When I try, I get this error message; The specified port(s) are being used by other configurations. Please check your ...
UPDATE: I solved the issue
When I initially configured the CAX80 I enabled the use of the built-in DHCP server to provide IP addresses beginning at 10.0.0.2 through 10.0.0.254. During this time of its use, I enabled the Port Forwarding option to a system with IP address 10.0.0.123 to test incoming conenctivity to a webserver I was hosting. After I confirmed it worked, I removed the port forwarding because I was not happy about the inability to restrict incoming IP addresses.As I proceeded to statically set IP addresses to a majority of systems in my home network, I subsequently modifed the range of IP addresses the DHCP server would assign to begin with .200 (through .254). Later, I decided to disable the use of the DHCP server entirely. However despite the option being greyed out indicating it was not being used, the reference to the beginning IP address 10.0.0.200 remained visible, though it too was greyed out.
Curious, I enabled the DHCP server, modified the beginning IP address to 10.0.0.2, saved the change, then disabled the use of the DHCP server. Once this was done, I was able to add the port forwarding rule.
To the OP, go take a look at the settings of the DHCP server. I suspect you might have been bit like I was.
My Gateway: Nighthawk CAX80
Firmware Version V2.1.1.4
Last week I configured the Port Forward option to a webserver (using TCP port 80) running on the LAN. I confirmed it was working correctly, but because there is no ability to restrict the incoming connection from a specific IP address, I subsequently deleted the rule as I did not want to leave it open/accessible to the Internet. Today, I proceeded to add it back, but I am receiving the same message as the OP. I am familiar with all of the options, but I confirmed the IP address of the involved system is *NOT* reflected anywhere else within the UI in use of any options.
If necessary I can provide a video demonstrating the issue, but these are the steps to reproduce:
1. Login to the CAX80
2. Go to Advanced
3. Select Advanced Setup
4. Select "Port Forwarding / Port Triggering"
5. With "Port Forwarding" selected, click the drop-down and select HTTP from the list.
6. In the Server Address field, type the IP address of the system to which Port 80 is to forwarded to, then click the Add button.
The response received is, "The specified port(s) are being used by other configurations. Please check your configurations of USB Readyshare, Remote Management, Port Forwarding, Port Triggering and UPnP Port Mapping table."
P.S. On a side note I noticed the ability to restrict incoming connections from the Internet to specific IP addresses on the Internet is NOT possible, despite the fact this was in fact possible with my Nighthawk AC1900. It seems the Port Forwarding / Port Triggering options available are inferior to what is offered on lesser devices, which is quite strange.

OMG! Thank you! This frustrated me to the max! Thanks to that other guy too, I know you were trying to help.
Are you referring to these settings in this image that's attached? I'm also having this port forwarding issue but I'm not sure what to be changing in that.
Unfortunatley offered solution did not work for me. At some point I was not able to add new port forwarding but old ones were fine.
After flipping DHCP switch old ones are gone too! Now I'm back to square one
Same here. I have most everything turned off and now can't set any forwarding. I had a rule set here last week but now it's broken. What the crap?!!
(also why is the CAX80 not an available model above?)
