Hi, it's about a month I'm getting mad with a similar issue... My ISP uses the port 8081 for TR069 so it's unavailable for any other usage. Since this port is the default used also by Diginet SW to transmit video channels, I changed it to 8086 into the server, the client and in Apache web server/page of my Diginet installation. Now everithing works properly, server, client, webdvr, but PDA sw seems to be not configurable and it doesn't work anymore. At this stage I think the only way to let it work could be to find a software that working locally on the PDA is able to re-address the port 8086 again to the 8081 before Diginet uses the data. If anybody knows a way to change port settings in Diginet PDA or about such "network port redirector" for PDA please let us know.
