The kernel parts of a sysctl that can switch on/off IP-in-IP (protocol 4)
support, when IPSEC is compiled in. The default is disabled. Turn on with:
sysctl -w net.inet.ip4.allow=1
***Only*** do this if you are really knowing what you do!
This control does not control the tunnel modes of ESP and AH.
