Apologies if this has been asked-and-answered elsewhere - I’ve looked but didn’t see anything obvious.
I have the Channels app loaded onto my iPhone. When I’m inside my house and connected to the local wireless everything is fine.
I’ve set up a VPN from the phone to the house ADSL router (Draytek 2860) which puts the iPhone onto the local network directly - there’s no NATing going on.
However, when I connect via the VPN I’m only getting the first 2 or 3 hours of the guide…scrolling forwards never loads any new information.
The VPN is correctly setup from what I can tell - the phone connects and correctly receives an IP address from the DHCP pool on the internal range (10.1.1.x in my case).
If I instead connect to the web interface on (http://10.1.1.2:8089/admin/guide/grid in my case) then everything works ok, it’s just the app that seems to have issues.
I’m guessing that the router isn’t passing some sort of traffic correctly, and I was wondering if anyone had any ideas? It’s not crucial but it is odd, and I’m curious 
Many thanks.
