Ok, that makes life easy :). As you can see in the logs, tinc is reading
from the tun/tap device on mia, it is sent to zidler, zidler receives
them and sends them to the tun/tap device. The only problem is that
zidler never sends a ping reply back.

One problem is that in zidler's tinc-up you have:

ifconfig $INTERFACE hw ether fe:fe:0:0:0:0

This should be:

ifconfig $INTERFACE hw ether fe:fd:0:0:0:0

Why you have to use this magic MAC address is a long story which I
probably should write down somewhere.

Furthermore, I see you use netmask 255.255.255.0 in both tinc-ups, that
should be 255.255.0.0 or you have to add an extra route somehow. But I
guess you already did something like that because otherwise the ping
packet wouldn't even go to the tun/tap device anyway.

Apart from the above, I don't see anything wrong!
