As described in my other thread I found a solution to get the port forwarding connection working with an Aiport router (Time Capsule).
The solution is to click on “configure” at the remote connection settings and to set it back from “Manual” to “Auto” and press “Save”. Afterwards set it back to " Manual" (and change ports if necessary) and press save. After a while (approx. 30secs) the connection changes from relay connection to port fowarding connection. Sometimes I have to repeat this 1 or 2 times
The problem now is that a couple of hours/days later the connection switches back to relay connection and I have to do workaround again. It seems to be a bug in the firmware and exactly the same happens with the WD my clouds of 2 friends of mine who are also using an Airport.
Can someone from WD with technical experience please look at the problem.
