One of the most underused features of all hardware routers is their logging function. Typically not enabled by default, logging can keep records of all incoming connection attempts from the Internet (both successful and not), as well as a list of all outgoing connections from your network. If you need or want to keep track of where users on your small network are ending up on the Internet, logging outgoing connections is very useful.
One downside of logging is that it presents you with source and destination IP addresses rather than names associated with incoming or outgoing connection attempts. If you want to find the name associated with the address, use the ping –a command followed by the IP address in question. To save log files you may need to install a utility from the CD provided with your router, and then specify the IP address of the system to which the logs should be saved.
