+Darwin and MacOS X
+------------------
+Darwin does not provide a tun(4) driver required for OpenSSH-based
+virtual private networks. The BSD manpage still exists, but the driver
+has been removed in recent releases of Darwin and MacOS X.
+
+Nevertheless, tunnel support is known to work with Darwin 8 and
+MacOS X 10.4 in Point-to-Point (Layer 3) and Ethernet (Layer 2) mode
+using a third party driver. More information is available at:
