@item You want to create virtual encrypted and authenticated 172.16.0/24
network and use it as a default transport.
@item Assume that outgoing GoVPN packets can be fragmented, so we do not
-bother configuring MTU of TAP interfaces. For better performance just
+bother configuring MTU of TUN/TAP interfaces. For better performance just
lower it and check that no fragmentation of outgoing UDP packets occurs.
