The "solution" didn't last: after a little more than 3 hours, this 
tunnel stopped working again :(

Strangely restarting openvpn on both sides fixed this, this time.

It's host B listening as a server: host A connects to it.
So I guess I should look into host B...

And no, "netstat -na" show no udp4 line with the choosen port, after I 
stop openvpn.



To my ignorance, this reminds me of the "no buffer space available" I 
sometimes get with ping.
That's just a wild guess, of course, but I suspect something is wrong 
with UDP on the "server" host...
