Just to follow up on myself - I'm in Italy now,
and everything works fine _except_ VPN.
I can ssh into my home server, get IMAP email from it,
and generally interact with it as I do at home,
If I ssh into my home server, ifconfig gives:
--------------------------------------------

while ifconfig on my laptop gives
--------------------------------------------

00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

As I point out, the P-t-P addresses are different -
I don't know if that is significant.
Also ping from my laptop gives
--------------------------------------------
[tim@mary ~]$ ping -c1 192.168.5.1
PING 192.168.5.1 (192.168.5.1) 56(84) bytes of data.
>From 192.168.5.1 icmp_seq=1 Destination Host Unreachable
--------------------------------------------
I'm not clear why it thinks it is pinging from 192.168.5.1
and not 192.168.5.6 .
Ping from the server gives
--------------------------------------------
[tim@mary ~]$ ping -c1 192.168.5.1
PING 192.168.5.1 (192.168.5.1) 56(84) bytes of data.
>From 192.168.5.1 icmp_seq=1 Destination Host Unreachable
--------------------------------------------
I guess I have not set openvpn up correctly on my laptop ...?
