Same issue with WZR-600DHP Firmware version: DD-WRT v24SP2-MULTI (11/04/12) std - build 20180
Also enabled Syslogd under "Services" and Log management under "Security" Tab... tried all different levels of logging in options, no log output.
Does there have to be a rule enabled in "access restrictions" for this to work ?
I tried the additional firewall rules under "SPI Firewall" Tab, no difference.
The blank logfiles below...
INCOMING LOG
Source IP Protocol Destination Port Number Rule
OUTGOING LOG
LAN IP Destination URL/IP Protocol Service/Port Number Rule
