Wallwatcher collects, displays and analyses log information from routers and firewalls. I recommend this tool to everyone who uses a firewall and router. Freeware of course download and see for yourself.

Some of the tools features include:
# filters let you choose what data and time periods to log, display, analyze, and chart
# alerts offer real-time visual and audible signals of possible intrusion attempts
# historical analysis helps you find patterns of recent intrusion attempts
# summaries condense log histories for easier review
# user-selectable charts let you spot patterns of suspicious activities.
