To change the NAT setting, go to Setup > System Options > NAT.
If you select to enable RTSP connection via public IP address, the IP address or domain name
will be automatically retrieved from the URL tab of the device web page. In order to see the
device’s webpage and streaming on the web page, both HTTP port and RTSP port should be
forwarded.
Suppose you set the IP address of the router to 112. 216.89.172 and forward the HTTP port to
8080 and RTSP port to 22230. Then, for the port forward setting:
1. Check the box of ‘Check this box to enable RTSP connections on a different port when the
unit is accessed via its public (NAT) IP address.’
2. Type the RTSP port number that your router knows. Check the RTSP port number stated in
System Options > RTSP/RTP.
3. Click the Apply button.
4. If you want to go back to the previous setting, click the Reset button.
When you use domain name, you should check out if the DNS or DDNS is enabled.
Go to System Option > TCP/IP for DNS setting.
Go to System Option > DDNS for DDNS setting.
If you want to access the webpage you should use the IP address of the router plus the port
number. (http://112.216.89.172:8080) If you do not configure the RTSP port forwarding
properly you will see the error message.
Prior to the NAT setting, the port forwarding of router should be done manually. It
does not provide any automatic NAT traversal service.
