Syslog not logging remote host

[Janos Dohanics]

I'm trying capture logs from m0n0wall, but the log file is empty.

Here is my configuration:

On the logging machine, in /etc/rc.conf:

syslogd_flags="-a 10.61.70.1"

In /etc/syslog.conf:

+10.61.70.1
*.*                                             /var/log/m0n0wall.log

/var/log/m0n0wall.log exists and writable:

-rw-rw-r--  1 root  network  0 Apr 13 00:32 /var/log/m0n0wall.log

The m0n0wall is configured to send logs to 10.61.70.100, which is the
logging machine.

What am I missing?
