DROP="`wget -qO- http://www.spamhaus.org/drop/drop.txt`";for i in `echo $DROP|egrep -o "[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}/[0-9]{1,3}"|sort -n`; do route add -net $i reject; done;EDROP="`wget -qO- http://www.spamhaus.org/drop/edrop.txt`";for i in `echo $EDROP|egrep -o "[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}/[0-9]{1,3}"|sort -n`; do route add -net $i reject; done

Fetches fresh rules, applies them - only using bash, wget, egrep, sort and route. No disk access - good for small routers.
