I /do/ in fact run the BIND on the same servers, and /do/ forward requests to the same servers primary address (IP). But on a different port eg; blackvoid.mydomain.COM { type forward; forward only; forwarders { port 530; }; }; Hell, this is right out of the BIND FAQ that comes with the FreeBSD BIND port. /However/, rbldnsd needs to /answer/ when it finds a match, and answers: IN A 127.0.0.2 REJECTED! evil spammer... So. This is what I mean by needing 127.0.0.? other than 127.0.0.1. Which brings me 'round to my original question: What has changed in 7 regarding 127.0.0/24 (lo0 || loopback). I have identical server setups/configs on 2 servers. The recent RELENG_6 server creates/provides 127.0.0/24 without question. While 7-RC3 only provides 127.0.0.1.
