Is pf enabled? Is $ext_if the interface for 24.147.135.133's packets? Why don't you try to replace <abuse> definition with table <abuse> const { 24.147.135.133, 24.147.135/24 } or any addresses you want and rule without iface: block in quick from <abuse> to any -- Regards, Anton Butsyk http://studiori.net/
