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. > Or host A has a zombie process with a UDP listen on the port? 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... bye & Thanks av.
