openvpn keepalive

Some experiments.  ubi <-> zoo.

The problem seems to be ping packets in the direction ubi->zoo.  If I
set my ping interval higher, I still get disconnects.  Sniffing it
seems that the OpenVPN ping is one-directional.  So it is my guess
that the ubi->zoo keeps some stateful firewall open, something with a
very low timeout.
