# Local and Remote should be 'any' or '::' but right now it does not work.
# However, by using the name "ip6tnl0" that matches the name of the interface
# automatically created when the kernel module is loaded it seems we can set
# anything "non-zero" here and the config will be accepted but still leaving
# "::" as both Local and Remote on the interface. This then results in the
# wanted configuration for now. One bug cancelling out another bug?
