I would consider doing it through BGP via quagga or such. Nullrouting with BGP is much cleaner than ACLs as your config stays static and only your routing table changes. I also imagine due to existing BGP blacklisting methods, that much of the work is already done and all you need is to get the honeypot to export the right format.

Honey pot that collects attacks against SSH/FTP and so on Said attacks are then sent to a master ACL on a edge Cisco router to block all traffic from these offenders .. Of course we would require a master whitelist as well as to not be blocked from our own networks. Any current solutions or ideas ?? -- BRW
