traffic analysis

[klxouthrunt]

I have a cisco 2811. I need a tool that can create reports of traffic analysis. I have seen that exists websense but is a payment tool and I need if could be a free software to monitor traffic of every ip and possible attacks to firewall

Thanks

Aside from Websence that work with the PIX firewall, there is also N2H2 which is now part of Secure Computing. Their product is now called Smartfilter. I think it is cheaper than Websence. I have not used it so I can not say how good it is.
