Firewall Log Daemon provides two programs, chaindaemon and tabledaemon, that you can choose between, depending on your firewall type (ipchains or iptables-netfilter). The program will start a small daemon process that parses and resolves firewall logs in real-time by reading a FIFO that syslog writes to. It will queue a batch of alerts and mail them to you. It features hostname, port, protocol, and ICMP type/code lookup, with formatted output for easy reading.
