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/
one. Changing all will affect all interfaces (which seems logical). The
default one probably affects interfaces being created (?)
