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?
