From Documentation/networking/ip-sysctl.txt:

conf/default/*:
        Change the interface-specific default settings.

conf/all/*:
        Change all the interface-specific settings.

conf/interface/*:
        Change special settings per interface.

        The functional behaviour for certain settings is different
        depending on whether local forwarding is enabled or not.

conf/all/forwarding - BOOLEAN
        Enable global IPv6 forwarding between all interfaces.

        IPv4 and IPv6 work differently here; e.g. netfilter must be used
        to control which interfaces may forward packets and which not.

        This also sets all interfaces' Host/Router setting
        'forwarding' to the specified value.  See below for details.

        This referred to as global forwarding.

forwarding - BOOLEAN
        Enable IP forwarding on this interface.

When you want to change a specific interface, use the conf/<interface>
one. Changing all will affect all interfaces (which seems logical). The
default one probably affects interfaces being created (?)
