Natd generates a message: "natd: failed to write packet back (Permission denied)". I saw that Natd tried to send icmp packages (answer) to some hosts. I think that Natd always tries to send icmp answer if it see package into internal network (unregistered addresses) from outside interface that has no entry in the internal table. How can I disable natd to send any icmp packages? I have another question about Natd. What does option "permanent link" mean? I didn't understand for what it need from manual pages. Many thanks, Mike Veselov. Ves@aep.mpei.ac.ru To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
