It is never a good idea to modify any file in /usr/share/shorewall. Next
time you upgrade, your change will get wiped out. The recommended method
is to copy the file you want to change to /etc/shorewall and then to
modify the copy.

A more straight-forward way to approach this would be to add the
appropriate simple DROP rules to your rules file.
