``conf/default/*``:
Change the interface-specific default settings.
+ These settings would be used during creating new interfaces.

``conf/all/*``:

[XXX: Other special features than forwarding?]
+conf/all/disable_ipv6 - BOOLEAN
+ Changing this value is same as changing ``conf/default/disable_ipv6``
+ setting and also all per-interface ``disable_ipv6`` settings to the same
+ value.
+
+ Reading this value does not have any particular meaning. It does not say
+ whether IPv6 support is enabled or disabled. Returned value can be 1
+ also in the case when some interface has ``disable_ipv6`` set to 0 and
+ has configured IPv6 addresses.
+
conf/all/forwarding - BOOLEAN
Enable global IPv6 forwarding between all interfaces.
