I am having the same issue as this gentleman.
I have set up DVR to DHCP which makes my router automatically pick up my DVR IP adderss etc
The ports that are currently forwarded in BT Hume Hub Fort Forward settings are:
Info Port: 3357
Video: 3358
Task: 3360
Web: 80
The above ports are also the only port options input-able within the DVR
Just like the person above - I have no option of "Mobile" settings within the DVR menu or manual. I can currently view from web in internet explorer from outside my network using (no-ip) DDNS however can NOT get the same to work from any mobile apps.
I have tried both MEyeProV6 and zMEyePlus and many other apps - none seem to work.
Any help will be much appreciated!
