I have set up 2 webcams at home to see my baby. These cams could be viewed properly with most other external computers

Since I changed to a new router last week, i can't view the webcams with my computer at work. However, the cams can still be viewed by other external computers (i tested this with computers at my sister's home, my parent's home, etc.). I've confirmed with my IT department that they haven't change any security setting to block my access.

I find it really strange that only some computers can access to the webcam but some cannot. What could possibly go wrong?

Thank you very much!

RotBlitz has already provided the most likely answer - your work is blocking access. The fact that you can access it from your sister and parent's houses says that the configuration at your end is correct.

To make it work from your job you'll need to talk to your IT support staff, preferably after you check that you're not going to get in trouble ;)

Well, everything seems to indicate that the port or protocol in question is blocked now by your employer's network nevertheless, or by your router. Did you possibly change the port on the new router? Or any other change in comparison to your former router? Also, without knowing your DynDNS hostname it is hard to figure out by us users what may be missing. (But I can understand you not discovering it.)
What you can try is to reach your home network in a more generic way:
telnet http://yourname.dyndns.org port-nbr
to see if you can connect. This only works if your company does not use a proxy server.

I have to agree with RotBlitz, it sounds like your work, their ISP or your ISP, are now blocking access even if by accident.

Can you provide:

  1. Your full hostname
  2. The port you use if you don't use port 80
  3. Whether those that can still access it use the same ISP as you

RotBlitz, I don't quite understand the meaning of (or how to) "telnet http://yourname.dyndns.org port-nbr"

What should I do?

I've set one of the cam with port 8000, av port 8002, internal ip 192.168.0.200 Another one with port 9000, av port 9002, internal ip 192.168.0.201

Port forwarding range: 192.168.0.200 - 8000 to 8010

192.168.0.201 - 9000 to 9010

I am not quite sure if I set anything else different to the previous router. I just simply follow the set up procedures told by the company that sold the cams to me.

When i try to connect to the cams at job, it does prompt me for user name and password (i've set password for the cams). It seems like actually it was successfully connect to the router and the cams. However, when it try to load for the image, it just got stuck there.

Any advise?

Thanks again. Much appreciated.

Open a command prompt and enter "telnet http://yourname.dyndns.org port-nbr", replacing http://yourname.dyndns.org by your hostname, and port-nbr by one of the ports you're forwarding. This is an easy diagnostic method to see if you can connect to your cams. Best is to execute this from outside.

Thank you very much. Will try.

I've tried but not successful. This is the system message: telnet is not recognised as an internal or external command, operable file or batch file.

What else can I do? Thanks.

If you're seeing the camera's login screen then see this thread.
