Perhaps.
1) In your example, the iptables_script class does not declare a
variable named "iptables_init", therefore with the classes as given,
it is natural that $iptables::iptables_script::iptables_init evaluates
to undef.
2) Your classes are notable for lacking any 'include' statements.
Generally, if you want to refer to a class variable that is outside
the current *lexical* scope then you should 'include' its class
somewhere in the lexical scope. This works only with unparameterized
classes, of course. Supposing that iptables_script declared the
wanted variable, you might do something like this:
class iptables_files {
include "iptables::iptables_script"
file { $firewall_top:
owner => "root",
group => "root",
mode => "0700",
require => File["$iptables::iptables_script::iptables_init"],
}
}
