Shorewall log messages are generated by NetFilter and are logged using facility 'kern' and the level that you specify. If you are unsure of the level to choose, 6 (info) is a safe bet. You may specify levels by name or by number. If you have built your kernel with ULOG (IPv4 only) and/or NFLOG target support, you may also specify a log level of
For most Shorewall logging, a level of 6 (info) is appropriate. Shorewall log messages are generated by Netfilter and are logged using the kern facility and the level that you specify. See shorewall-logging(5). Similar to LOG:ULOG [(ulog-parameters)], except that the log level is not changed when this ACTION is used in an action or macro body and the invocation of that action or macro specifies a log level. In a Shorewall logging rule, the log level can be followed by a log tag as in "DROP:NFLOG:junk". The generated log message will include " chain-name junk DROP". By setting the LOGTAGONLY option to Yes in shorewall.conf (5) [8] or shorewall6.conf (5) [9], the disposition ('DROP' in the above example) will be omitted. What I don't know, is how I can tell ulogd2 to write all shorewall messages to my desired log file /var/log/shorewall. The documentation is rather unclear on this, as this forum thread testifies. This blog post I found is equally vague, regarding ulogd2 's log redirection. Beginning with Shorewall 5.0.0, the log level may be followed by a colon (":") and a log tag. The log tag normally follows the packet disposition in Shorewall-generated Netfilter log messages, separated from the disposition by a colon (e.g, "DROP:mytag"). See LOGTAGONLY below for additional information. Example: LOG_LEVEL="NFLOG(1,0,1)" Beginning with Shorewall 5.0.0, the log level may be followed by a colon (":") and a log tag. The log tag normally follows the packet disposition in Shorewall-generated Netfilter log messages, separated from the disposition by a colon (e.g, "DROP:mytag").

Trying to understand how it works and my little knowledge of programming, I have come across, that I would like to ban who appear as DROP on my shorewall log, the jail will set the number of DROP required in a length of time. My problem is that I don't know how to make a proper failregex for the shorewall log.
Shorewall events were introduced in Shorewall 4.5.19 and provide a high-level interface to the Netfilter recent match capability. An event is actually a list of (IP address, timestamp) pairs, and can be tested in a number of different ways: log_level specifies logging for the generated rules. Note.
