</span>If the remote nodes want to communicate with each other, then if<br>
possible they will do so directly without going through the central<br>
node. However, if that is not possible for some reason (because of NAT<br>
for example), then it will go via the central node. But in that case,<br>
the tinc daemon on the central node will handle the forwarding<br>
internally, you will not see those packets when you run tcpdump on the<br>
central node's tun0 or eth0 interfaces (but if you set Forwarding =<br>
kernel on the central node, then you will see the packets on tun0).<br>
