[syslog-ng]iptables & syslog-ng

Hello, I just set up an iptables based firewall on my syslog-ng host machine (redhat 7.1), but ran into a small problem. When I run syslogd+klogd, I can see iptables generating the logfiles. When I disable the standard syslog daemon, and run syslog-ng+klogd, I do not see the data I am looking for, it is almost like iptables isn't logging at all, but it has to, since it works with the normal syslogd. I setup a generic rule, and a fallback, so everything should work. When using the "logger" tool, and generating a fake entry, everything seems ok, so I assume this is an issue between kernel logging and syslog-ng. I am running 1.5.9 (not the official release). Any help would be appreciated. Thanks Best regards, Daniel
