DD-WRT can use the syslog and klog daemons to log system, kernel, and firewall events. This can be useful for troubleshooting purposes, or just to keep an eye on how your router/network is behaving.

  1. Enable Syslogd under the Services tab.
    • If you wish to send logs to a remote system, enter the IP 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).
  2. To log firewall events, go to the Security tab and enable the appropriate options.

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 you specified earlier.

Recommended tools (if logging remotely):
syslog-ng (CYGWIN)
Kiwi Syslog

Linux already has syslog built in.
