I can't figure out why my whitelist entry for 204.238.179.0/24 is being ignored. If not for a transient DNS failure this afternoon I'd not have known this was broken. The check_client_access whitelist entry _should_ have triggered before reject_unknown_client_hostname. Any ideas why is doesn't/didn't?
