Link-n-Log allows you to capture the log files from Linksys firewalls/routers. It has been extensively tested with the BEFSR41 but should also work with the BEFSR11, BEFSR81 and probably any of the other BEFSR family of routers. The application consists of a GUI to view the alerts and a Daemon process to capture the SNMP traps emitted by the Linksys device (the routers use SNMP to send transmit their log files). The GUI can display all incoming and outgoing connections, perform DNS lookups on the source or destination of any connection and can do port lookups to indicate what ports correspond to which servcies. The port lookup database was provided by the good people at Neohapsis.com. All the connection data is logged to a MySQL database so you can use tools other than the Link-n-Log GUI to view and manipulate it if you want.
