AT_HOME_RANGE="213.51.16.0/21 213.51.24.0/21
	 
 ${ECHO} -n "Drop and log @HOME_USERS in range: "
    for athomerange in ${AT_HOME_RANGE} ; do
           ${IPTABLES} -A INPUT -i ${EXT_INTERFACE} -s ${athomerange} -m limit 
\   
               -j LOG --log-prefix "@HOME_USER:DROP "
          ${IPTABLES} -A @HOME_CHK -i ${EXT_INTERFACE} -s ${athomerange} -j 
DROP
        ${ECHO} -n "${athomerange} "
  done
  
this is an example off a line i use  , if you wish to have more ranges, you 
have to make a new rule like this ,but another name like "AT_HOME_RANGE2" 

good luck
