If you are on Puppet 4 or later, then you should be using the lookup()
function instead of the deprecated hiera() family of functions. On Puppet
5.5 and later (and perhaps on earlier 5.x releases) that has the particular
advantage that lookup() is documented to support the dotted key / subkey
notation you are trying to use, whereas hiera() is not documented to
support that on any version of Puppet. The error message you present is
characteristic of this problem: the system is attempting to interpret the
whole string "iptables::test.ip" as an Hiera key, instead of recognizing it
as a separate key ("iptables::test") and subkey ("ip").

On recent-enough Puppet, just switching from hiera() to lookup() will
probably resolve the issue:
$variable1 = lookup('iptables::test.ip')
$variable2 = inline_template("<% @variable1.each do |key,value| %>Allow
>From <%=key %> #<%=value %>\n<% end -%>")
Alternatively, look up the top-level key, then extract the wanted data from
it separately, for example:
$variable1 = lookup('iptables::test')
# or $variable1 = hiera('iptables::test')
$variable2 = inline_template("<% @variable1['ip'].each do |key,value|
%>Allow From <%=key %> #<%=value %>\n<% end -%>")
