Description of problem:

The "log" option appears to be completely ignored for the "forward-port" rich rule. There's no error, add-rich-rule succeeds, but a logging iptables rule does not get created.

Version-Release number of selected component (if applicable):

firewalld-0.3.14.2-4.fc23.noarch

How reproducible:

always

Steps to Reproduce:
1. The default rsyslog.conf in fedora logs all *.info messages to /var/log/messages
2. Add a forward-port rule with the "log" option. For example:

firewall-cmd --add-rich-rule 'rule family="ipv4" forward-port port="8369" protocol="tcp" to-port="80" to-addr="192.168.0.2" log level="info" limit value="1/h"'

3. Use telnet, appropriately, to establish a new connection that uses this NAT rule.

Actual results:

Nothing gets logged to /var/log/messages

Expected results:

According to the firewalld.richlanguage man page, I can expect to have the connection logged via syslog:

   Log
           log [prefix="prefix text"] [level="log level"] [limit value="rate/duration"]

       Log new connection attempts to the rule with kernel logging for example
       in syslog. 

Additional info:

Examining what firewalld does with iptables, it doesn't look like there's any iptables LOGGING entry. I see the forward port rule in the nat table, and that's pretty much it.
