Unmanaged deviced are defined via plugin-specific way. See
man NetworkManager.conf
For Fedora/RHEL put NM_CONTROLLED=no to /etc/sysconfig/network-scripts/ifcfg-
eth0 (eth1, etc.)

"no-auto-default" only list interfaces for which a default connection (Auto 
eth0) shouldn't be created (in case no other connection is available for the 
device). It has nothing in common with unmanaging interfaces.

I think NM sets ip_forward just in case the method is "Shared to other 
computers" to allow forwarding packets.
