IP cam & port forwarding

JTM has brought this to us :

I'm on a dynamic ISP issued IP. My German (Chinese made) camera comes with what I think you are lacking - It allows me to set up an account with the manufacturers web site, which keeps a constant record of the latest dynamic IP. I'm guessing what happens is that the camera constantly reports my ISP's IP to the site, then when I try to log into the camera it logs in via the manufacturers site.

I have seen this problem using the Meye apps for camera viewing. I suspect you are possibly using a non optimal app. I found EZeye to work correctly with Android and i devices. Using IE the system has always worked. The ddns system always works correctly IME.

It looks like you have the right forwarding settings.

You may also need to add a rule to the routers firewall however to allow the inbound traffic.

I would not bother with DMZ settings.

You could temporarily change your forward rule to point at a PC rather than the camera. Then run wireshark on that, check that the router really is forwarding the incoming connection.

Also check to see if the router has any logging capability. You might find that it can record useful information.

Mm... have you tried a direct connection to that port with e.g. telnet?

It does look like port 1533 is open, but that isn't enough.

Suggestyou do a 'view source' on the actual picture link when you CAN see it to see whether it actually includes something else.

What mobile device are you using? Mobile ports frequently use port 100.

Where are you running the test from? The same location as the camera?

Many routers don't support something called 'NAT loopback' (or variations thereof). Whilst the router is able to port forward from the WAN to the LAN it might not be able to do this for LAN clients. What router is it?

It'd be worth checking from somewhere else, even just a mobile using its GSM connection (i.e. not your local wifi).

Mobile devices can, and do, use the same range of ports as any other device.

Is this link of any use?

Is that address correct? Mine is xxx.xxx.xxx.xxx.ccc then the port. I find it is necessary to input all the digits in order to have the thing work.

Those pesky Chinese with their 40 bit IP addresses huh!

OOPs My error. Only 4 groups.

Yep

This seems to have been the problem. got the camera to trigger an alarm email to daughter in UK and while I spoke to her by phone she logged in. Thanks everyone!

Now I can check the place out on iPad or iPod touch when I'm away from home

So now you get a ruined holiday as well as a burgled house. Great ;-)
