+# Optional for 6to4 tunneling (hardwired name of tunnel device is "tun6to4"):
+#  IPV6TO4INIT=yes|no: controls 6to4 tunneling setup
+#  IPV6TO4_RELAY=<IPv4 address>: IPv4 address of the remote 6to4 relay (default: 192.88.99.1)

+# Optional for 6to4 tunneling to trigger radvd:

+#  Required version of radvd to use 6to4 prefix recalculation
+#   0.6.2p3 or newer supporting option "Base6to4Interface"
