My IP cam model is Genius 350TR, I tested the cam at home on lan and internet and it worked. Then I shifted it to an office. It works on the office lan setup but I cannot connect to the ip cam from home.

The IP cam is configured for port 192.168.0.30:7070 and it has a port forwarded to publicIP:7071

When I telnet to that public IP it connects to that port. However when I try to access the ip cam from a web browser it only shows me the configuration page and settings and the video is blank and it says connecting for some time and then says disconnected. The cam is configured for HTTP on internet and UDP on Lan.

The office setup is ISP ---> WifiRouter ---> PC With Wifi card ---> Switch ---> IP CAM

Is there a way to debug this problem?

Does the wifi router connect to the switch? –  Greg Askew Jun 21 '12 at 9:11
    
@GregAskew: No. The switch is connected to the ethernet connected of the PC with Wifi card. The Wifi and ethernet connections are bridged. –  Kevin Boyd Jun 21 '12 at 9:20
    
Wow, that actually works? ;-) –  Greg Askew Jun 21 '12 at 11:55
    
@GregAskew Lol! What did you expect? –  Kevin Boyd Jun 21 '12 at 12:50
    
@KevinBoyd: One would expect it not to work. The access point is not supposed to forward frames to a client unless the packet's hardware destination address is the address of one of its clients. Since the IP CAM is not a client of the WiFi router, it should not forward packets destined to it to the PC. This is why you have to configure WDS in both access points. (Likely, your PC is providing some unusual form of NAT where it rewrites the hardware addresses, much as some Wifi routers do in "client bridge" mode.) –  David Schwartz Jun 24 '12 at 9:37

My opinion is, that camera have video stream on another port. And if you don't have forwarded port for video stream too, you cannot see a video in the browser. In some cameras you can configure ports for video, then you can see, which port you have redirect too. If this camera don't have port in configuration, try nmap or some similar tool to scan, which port on the camera is opened...

EDIT:

You can see this port in HTML of web page, where is empty place for video... Try to use 'Ctrl+u' on this page in your web browser, this is usually shortcut for 'preview HTML', and try to search in the HTML code.

I recheced my camera settings and it shows 3 ports, HTTP (7070), RTSP(554) and stream(53). At the moment the HTTP port is forwarded but not RTSP and stream. Do those need to be forwarded too? Regarding nmap can it be nun on Windows? –  Kevin Boyd Jun 21 '12 at 9:15

You are know, which ports you have to redirect... :-) Stream port and RTSP port. –  Jan Marek Jun 21 '12 at 9:20

nmap works on windows... See nmap.org/download.html –  Jan Marek Jun 21 '12 at 9:22

Please, try to forward: http port cam -> router:7071, 554 port cam -> router:554. Don't forward port 53, because it is the same port as DNS. –  Jan Marek Jun 22 '12 at 11:10

In the UNIX world, the important port number are less than 1024. But there can be other services, which have port higher than 1024, say 5060 for SIP... Try use a google whith question IP port xyz, you will see, if it is free... –  Jan Marek Jun 22 '12 at 16:40
