my landline only has an IPv6 address (well in addition IPv4 via crappy DSLite). I'm anyway trying to set up an owncloud server at home and access it from remote locations. So the task by now is to access the owncloud server via IPv6 using my Android 5.0.0 phone (Moto G 2014).
If I open the IPv6 address in my browser on the phone while connected to the same WiFi as the owncloud server everything works fine. But once I turn off WiFi and switch to cellular data the server can't be accessed anymore even though my router is configured to pass every connection to the owncloud servers IPv6 address range. This result is still reasonable since via the mobile network I only have an IPv4 address and no IPv6 address, so I can't communicate directly with an IPv6 target.
Are there some tricks to still reach an IPv6 host through an IPv4 connection on Android? Using tunnels ect? Or is this completely impossible by design?
Thanks a lot for replys!
