Debug logs can be very useful in figuring out why problems are happening and how to fix them.
By default, logging on DD-WRT is turned off. To enable it:
Enable Syslog under the Services tab.
If you wish to send logs to a remote system, enter the IP address of that machine which is also running a syslog utility (it needs an open network socket in order to accept logs being sent by the router).
- To log firewall events, go to the Security tab and enable the appropriate options under Log Management. (Note: this doesn't function in micro)
That's all there is to it. DD-WRT should now be logging, either locally to /tmp/var/log/messages, or remotely to the IP address you specified earlier.
