[syslog-ng] Can't get basic syslog to work for my firewall logs?

[Tim Tyler]

Syslog-ng experts.

  I am very new to syslog-ng.  I installed syslog-ng on a fresh Redhat 7.3
server.   It defaults working with internal logging.  So I configured my
firewall to send syslog with facility set to log_user.  I turned on
Wireshark on the syslog-ng server and observed the firewall sending traffic
to the server on udp 514.



But the syslog server never created the directory structure and logs.  I
disabled the redhat firewall just to eliminate it as a possibility.  Still
no logging.  So I don’t know what I am doing wrong at this point. I don’t
know if this is a permission problem or some other configuration issue.  I
found someone that had posted a very basic syslog-ng configuration for
firewalls.  So I copied It into a firewall.conf I put in conf.d.  Can
anyone see what might be wrong with it?
