I tried to using iptable kernel message with this nat kernel. Therefore I installed sysklogd and removed simple-syslog-deamon. However klogd is complaining: kernel: Cannot find map file kernel: init: klogd main process terminated with status 1 So it seems that the System.map file for the Kernel is missing. @jackburton/ juiceme any chance that you get such a file when compiling the kernel. Is in your kernel config "CONFIG_IP_NF_TARGET_LOG" enabled? I see that in the btlc kernel it is not activated. Can somebody compile a nat kernel with this module activated please? Or has somebody in general a clue?
