Network Camera

I installed a Panasonic Network Camera at our remote site. This camera is accessible through a web brouser (IE or Netscape) when you enter it’s IP address. At the remote site, it works fine.
Now, at my local site, I’ve configured my PC to the router which this camera is connected to making it possible for me to ping to the camera. I am trying to gain access to the Camera from my browser just as the remote site by all to no avail! What do I need to do to be successful?
