Hm, that is strange, once a connection has been made through NAT it should keep
working, unless the connection timeouts on the NAT device are set very small.
You could try setting "PingInterval = 30" in tinc.conf to have tinc send ping
packets more often.

Tinc should determine it itself. If it does not, that is a bug. It can take a
minute though for tinc to detect that UDP has failed to work. Does it still not
work for you after more than a minute?

They will be in one TCP session.
