If you're using sshd as a daemon have a look at "ListenAddress"
directive in /etc/ssh/sshd_config. You can have multiple of those.

How about adding 'syslogd_flags' in /etc/rc.conf? Those are the defaults:

# grep syslogd /etc/defaults/rc.conf
syslogd_enable="YES"            # Run syslog daemon (or NO).
syslogd_program="/usr/sbin/syslogd" # path to syslogd
syslogd_flags="-s"              # Flags to syslogd (if enabled).

Also, if you don't need it to bind at all it's better to use '-ss'.

You could filter traffic at firewall but it's always better to have a
simpler setup.
