How to view Camera connected to internet through DVR

[ishanbatra]

Hi

I want to watch the cameras installed at my home over the internet from anywhere.

For that I have connected my DVR to my router(connected with ADSL modem) and added the 3 ports mentioned in dvr settings in the port forwarding of my router and set the dvr in DMZ.

Now when I view the camera over lan it works fine but when I try it over the internet then I have a problem.

When I enter the external IP address a popup appears asking for username and password.

I tried entering the username and password of DVR, Router and Modem but nothing works. It says login failed.

I dont know why. How can I resolve this issue?

PS: My modem has dynamic IP and no ddns settings enabled. But I should be able to view the camera still, I just need to re-enter the IP when it changes? Am I right about it?
