Am trying to get RealVNC Server working right on my RPi3 running Jessie. Have the RealVNC Viewer on my iPad. Am starting with the free version to evaluate it and will upgrade to get encryption later.
RealVNC Server gives me an IP address to use to connect to it, and when I use that IP from the same network, it works but has a sluggish response time. The IP address begins 169.254.xxx.xxx and is not in a form that my router recognizes which should be in the form 192.168.xxx.xxx.
When I try to set up external Internet access, my router will only forward ports to IP addresses in the form 192.168.xxx.xxx. Therefore I can't get external access.
Also, my router does not show that it is connected to the RPi in the device list. However, from the RPi it should that it is associated with my router network. But I don't have an IP address for the RPI in the form 192.168.xxx.xxx.
Any suggestions on how to get this fixed? RealVNC won't help because I'm not using the paid version. Of course, the absence of support doesn't make me feel good about buying the upgrade!
