No!
You should make the following changes:

          for OURIP in ${SERVER_IPS}; do
            for PORT in 20 21; do
             ${FWIN} -p tcp -d ${OURIP} --dport ${PORT} ${OK}
-            ${FWIN} -p tcp --sport  ${PORT} -d ${OURIP} --dport 1024: "!" --syn ${OK}
+            ${FWIN} -p tcp -d ${OURIP} --dport 1024: ${OK}
             ${FWIN} -p udp -d ${OURIP} --dport ${PORT} ${OK}
-            ${FWIN} -p udp --sport ${PORT} -d ${OURIP} --dport 1024: ${OK}
+            ${FWIN} -p udp -d ${OURIP} --dport 1024: ${OK}
            done
          done

This helps for me.
