OK.
No router connected at all, so no port forwarding issues.
Got a crossover cable from next door.
Ping fails.
Video server E finds DVR on port .1.10 Video Server E connects using admin as password. Browser can not connect to DVR. See's DVR but fails to connect.
Plug back into HUB, Video server E finds DVR on port .1.10. Browser can not connect to DVR. See's DVR but fails to connect.
DVR is 100% definately setup to access as a STATIC ip and at .1.11!!!
Connect to router and other computers, and DVR is still at IP .1.10
Power cycle all equipment, and retest - DVR at ip .1.10
DVR still shows IP as STATIC and at .1.11
Browser can not connect to DVR. See's DVR but fails to connect. to first page.
Video E software runs perfectly on the wrong IP address through the full network.
Actual problem solved - ie I can download the video.
I changed the static IP address to .1.100 and Video E fails to connect to new IP and fails to connect to .1.10. Change to .1.10 and failure to connect. Change back to .1.11 in desperation and connection made to .1.10 with video E. Browser connection simply does not work in any case.
Why on earth this works like this - I do not know.
Browser failure - Shows logon screen, when logon complete displays message "The requested URL was not found on this server " - The new URL was
http://192.168.1.10/home.cgi which it changed to when I pressed enter.
No logon screen at
http://192.168.1.11 Which is the actual set IP address for the DVR
