JayADee: Ok so the cameras are working fine over the fritzbox's Fritz VPN but you can't browse the internet using the fritz's VPN so you have to switch the vpn on on your phone/iPad to view the cameras then off to get back online. My spouse will hate that.
Is there another free VPN I could set up in the Fritz that would let me just leave it on all the time? I don't need yet another bill to rent a VPN.
I know I could just use Dahua's built in P2P but I believe VPN is recommended.
This is not an issue limited to FritzBox's VPN. Its more the client supporting the ability to toggle sending all traffic over VPN. Many clients on Mac and Windows allow you to toggle this option. Not sure on the FritBox config anymore sorry as I don't use FritzBox setup. I use an OpenVPN setup with my Synology and this works OK.
