I would start by reading:

 http://www.shorewall.net/3.0/configuration_file_basics.htm#MAC
 http://www.shorewall.net/3.0/configuration_file_basics.htm#Variables
 http://www1.shorewall.net/3.0/configuration_file_basics.htm#Continuation
 http://www.shorewall.net/3.0/Actions.html

Then I would configure files as shown below.

/etc/shorewall/policy:

loc     mz      REJECT  info

/etc/shorewall/params:
#
# List the 20 macs here in Shorewall format
#
MACS=~00-01-02-03-04-05,\
~01-02-03-04-05-06,\
...
~AA-BB-CC-DD-EE-FF-00

/etc/shorewall/actions
#
# Declare action 'AcceptMacs'
#
AcceptMacs

/etc/shorewall/action.AcceptMacs
#
# Define the Action (Accept from any of the listed MAC addresses)
#
ACCEPT          $MACS

/etc/shorewall/rules:
#
# Send all loc->mz traffic through the AcceptMacs action.
#
AcceptMacs      loc     mz      ...
