n2n edge connection times out

[emanuele-f]

I have noticed that n2n sometimes stalls when there are a lot of packet drops due to unreliable communication channel. Restarting n2n on both the edge nodes solves the issue, so I suspect some metadata n2n packets (e.g. registration) are dropped and not retransmitted. I will provide more information when I reproduce the problem again.

When an edge is started and no traffic is sent (idle) it might lose the connection.
A way to keep the edge nodes up is to keep pinging the edge ip from a node on the network.
This is currently the only way I can keep the network up.
