Export iptables logs to network storage in a limited storage dd-wrt router

Question

Because some routers have very limited storage space; security logs are disabled in the micro version of dd-wrt. Is it possible to export the (iptables) logs to an external storage?

Why don't you just log to a remote syslog server? – Michael Hampton Jul 02 '13 at 21:48 — Michael Hampton, Jul 02 '13 at 21:48

Yes you can log to a remote syslog daemon. The default program will truncate long messages. If you have memory your can use syslog-ng. Installation should be similar to my installation of Syslog-ng on openWrt.

I can't install anything on the router it's 2Mb flash only. – AK_ Jul 03 '13 at 08:41
In that case, you should be able to specify the IP address of a server running a syslog daemon. You will need to configure it to listen for network messages. Then configure the router to log to that IP address. – BillThor Jul 03 '13 at 11:34
