Well probably.
Originally it was setup to connect with ADSL when we only used standard copper broadband. After the fibre upgrade I had the Plusnet Hub one. I admit I didn't check access to the iplayer then. After a couple of days I switched that into modem only mode and the DGND4000 in router only mode.
Then I decided I would like to be able to setup opendns which the plusnet box didn't allow, so I purchased the Netgear DM200 VDSL modem/router. To get this all working I factory reset both units, checked S/w upgrade, switched the DM200 into modem only mode and connected to the WAN port of the DGND4000. I then set about fixing the port forwarding as required.
Generally everything is now working OK apart from the Iplayer on the TV or via the Humax freesat box (both LAN connected) or the NOWtv box (wireless connected)
I am not aware of any particular setting that would enable/disable the BBC Iplayer especially seeing that the Youtube , netflix and other apps work fine.
I will check by restoring the Plusnet Hub one for a while.
Thanks for any suggestions.
