I am using 4.8

i think it was a problem with rc.network.
even it says 

log_in_vain="0"  # >=1 to log connects to ports w/o listeners.

in /etc/defaults/rc.conf.

rc.network is

<code 1>
network_pass4() {
        echo -n 'Additional TCP options:'
        case ${log_in_vain} in
        [Nn][Oo] | '')
                ;;
        *)
                echo -n ' log_in_vain=YES'
                sysctl -w net.inet.tcp.log_in_vain=1 >/dev/null
                sysctl -w net.inet.udp.log_in_vain=1 >/dev/null
                ;;
        esac

        echo '.'
        network_pass4_done=YES
}
</code>

this is fixed in stable as far as i see.
<code 2>
network_pass4() {
        echo -n 'Additional TCP options:'
        case ${log_in_vain} in
        [Nn][Oo] | '')
                log_in_vain=0
                ;;
        [Yy][Ee][Ss])
                log_in_vain=1
                ;;
        [0-9]*)
                ;;
        *)
                echo " invalid log_in_vain setting: ${log_in_vain}"
                log_in_vain=0
                ;;
        esac

        if [ "${log_in_vain}" -ne 0 ]; then
                echo -n " log_in_vain=${log_in_vain}"
                sysctl net.inet.tcp.log_in_vain="${log_in_vain}" >/dev/null
                sysctl net.inet.udp.log_in_vain="${log_in_vain}" >/dev/null
        fi

        echo '.'
        network_pass4_done=YES
}
</code>

in code 1 log_in_vain=* results it to be log_in_vain=1
if it is not NO 

in code 2 log_in_vain="0" works as predicted ...

solution :

1 - put "log_in_vain="NO" into /etc/rc.conf
2 - modify your rc.network --- 

i did the second for my box and gone to single user 
and back to multiuser and there was no problem ..

Ps : code 2 is from src/etc/rc.network and 1 is 4.8's version
