Troubleshoot port forwarding. Could it be ISP blocking incoming connections?
- by Gravy
Had a new Axis IP camera delivered yesterday. Plugged into Cisco E2400 Wireless Router but having problems.
Example topology:
WAN IP: 10.10.10.10 (example)
Cisco Router: 192.168.1.1
Axis Camera: 192.168.1.10:80
Port forwarding rules set up on router
External Port: 999
Internal Port: 80
Protocol: TCP & UDP
Device IP: 192.168.1.10:80
Enabled: True
Trying to connect from within the lan to 192.168.1.1:80 from within browser - Works properly.
Trying to connect from within the lan to 10:10:10:10:999 from within browser - Works properly.
Trying to connect from outside the LAN (e.g. via 3g or another isp) to 10:10:10:10:999 from within browser - Doesnt work.
I get the following errors from different machines / browsers:
Safari could not open the page because the server stopped responding (IOS)
The server at xx.xx.xx.xx is taking too long to respond. (firefox)
This problem is not just for the Axis camera. I am also having similar problems connecting to my NAS drive.
After using a web based port scanning tool, it appears as though port 999 is closed. Not certain why when I have set up port forwarding within the router.
Any troubleshooting suggestions to help me determine whether the problem is with my Cisco settings / firewall or whether it could be my ISP blocking incoming connection requests?
Many thanks
