That is correct. And indeed with Forwarding = off, those packets are dropped,
that is exactly what this option is meant to do. Why do you want to use
Forwarding = off?

64 nodes is not an unusual number for tinc. In what way does the network become
unstable?

There is no limit in tinc itself, but if you have slow network connections it
can take a while for tinc to exchange metadata between nodes. If it takes too
long, it might close connections. You can try to increase the value of
PingTimeout in that case.

It should not be noticably slower, but if you have a lot of nodes joining and
leaving all the time it might.
