I also have a 942L
URL examples for DCS-942L:
Local:
http://192.168.1.35/video/mjpg.cgi
Remote:
http://seemyreef.dyndns.org:8080/video/mjpg.cgi
In the remote URL, use your router's public IP address or dynamic DNS hostname, and the public port number you used in the router's port forwarding fo the camera.
BTW, if you have not discovered it yet, the 942L with the most current firmware has a known big problem with using night (infrared) mode even when there is plenty of ambient light.... no color, just grayscale video The solution is to disable night mode - at least until D-Link fixes it in a firmware update.
