If one end or the other is doing dynamic NAT, the UDP entries
are timing out in periods of no activity. If possible, make
the NAT static - if not, set up a ping or something to generate
traffic often enough to maintain the NAT table entry.  If you
aren't using NAT you can have a similar issue with firewalls
that dynamically allow return packets to the source of UDP
packets.  You can fix that by configuring it to always allow
the CIPE packets based on source, destination and port.
