My inside computers (win2k, slackware and win98) need to be totally invisible to the outside. Does natd/ipfw hide the inside MAC and IP address ? Do I need to take any special precautions ? thanks, Voutah To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ipfw" in the body of the message
