I have managed to successfully establish an IPSec IKEv2 connection from my RUT240 (to an Azure VPN Gateway).
However, I am then not able to ping or connect RUT-->Azure.
Surprisingly, I am able to ping Azure-->RUT, after which the connection seems to "open" and I am able to connect RUT-->Azure.
This doesn't seem to last though. Over night the problem returned and I had to repeat the trick of first pinging Azure-->RUT.
What configuration settings could be missing?
The tutorials suggest that it should just "work" after setting up the IPSec connection.
