However, it is not strictly necessary that you call tinc with the -n

If your computer has more than one IP address on a single interface (for

address.

This option controls the time the encryption keys used to encrypt the data

impossible to crack a single key.

This option specifies whether other tinc daemons besides the one you
specified with ConnectTo can make a direct connection to you. This is
especially useful if you are behind a firewall and it is impossible to
make a connection from the outside to your tinc daemon. Otherwise, it
is best to leave this option out or set it to no.

If this variable is set to yes, then the packets are tunnelled over a
TCP connection instead of a UDP connection. This is especially useful
for those who want to run a tinc daemon from behind a masquerading
firewall, or if UDP packet routing is disabled somehow. This is
