Check the output of "sockstat -4" to ensure that you don't have anything running that you aren't aware of ... syslogd is a typical culpret. You'll probably have to add syslogd_flags="-ss" to /etc/rc.conf Otherwise, you're probably good, execpt that there are some spoofing techniques that may be able to get around such a ruleset. That's beyond my expertise, however. -- Bill Moran Potential Technologies http://www.potentialtech.com _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
