Can anyone tell me the difference between what these kernel variables do?  

Does the first one have to be set before the second will work or are they independent?

/proc/sys/net/ipv4/* Variables:

  ip_forward - BOOLEAN
        0 - disabled (default)
        not 0 - enabled 

        Forward Packets between interfaces.

        This variable is special, its change resets all configuration
        parameters to their default state (RFC1122 for hosts, RFC1812
        for routers)

/proc/sys/net/ipv4/conf/interface/*: 
/proc/sys/net/ipv4/conf/all/* is special and changes the settings for all interfaces.
        Change special settings per interface.
  forwarding - BOOLEAN
        Enable IP forwarding on this interface.
