dd-wrt local AND remote syslog

syslog.txt

dd-wrt supports remote and local syslog at the same time
However this is not supported by the GUI
You need to invoke syslogd as follows:
~#: syslogd -L -R <host-ip>[:<port>]

You can further adopt this e.g.
~#: syslogd -L -b 5 -s 2000 -R xxx.xxx.xxx.xxx:xxx

You can run this script at startup to kill the system started syslog (either syslogd -L or syslogd -R ....)
and start it with your arguments:
sleep 2
killall syslogd
/sbin/syslogd -b 5 -s 2000 -L -R xxx.xxx.xxx.xxx:xxx


dd-wrt trac marks this as resolved by changeset 23625 (http://svn.dd-wrt.com/changeset/23625)
I tested this on a rather old SVN revision 18024 and it works

Output of syslogd --help (taken from https://www.dd-wrt.com/phpBB2/viewtopic.php?p=713411 
since my router does not support this)
