On the other hand, NJABL.ORG lists 255K open relays, 170K open proxies, and a spattering of dialups and other listings. This is way beyond ACLs that I could even imagine thinking about :-)
anyone who was facile with perl could transform a full list of open relays or proxies into something that avibgpd could use, so that you could have your access controls implemented as routes rather than acl's. if you combine that with policy routing so that you can blackhole traffic based on source rather than destination, you could get the added benefit of not having to take/deliver the SYN only to blackhole the resulting SYN-ACK. -- Paul Vixie
