I'm trying to get an Edimax 9110W camera set up so that I can view it on the web.  The web connection is 2d fibre with the camera at local fixed IP 192.168.178.45.  I can see the camera at that address with a browser. All looks fine.  I'm trying to get the same access going over the net.  I've tried all sorts of black magic but nothing works. The 2d connection is fixed IP so there is no dynamic DNS involved.

I'm sure it's the port forwarding that unsticks me.  I'm not sure how to set that up.  The FB has assigned two random-sounding ports as externally available  

Using https://www.yougetsignal.com/tools/open-ports/ I can see that:

    1443 is closed
    80 is closed
    15136 is open
    26956 is open

whenever I access the page I get a username password prompt which will not accept the username and password I created specifically to access the camera.

What I'm hoping is that someone has the above configuration working, and then I can clone the settings they are using.  At the moment I am floundering.  There are too many combinations of settings I don't understand.
