That is, if you run ntpd on a directly internet-facing machine. In most scenarios involving NAT, the NAT happens in a router/firewall/modem appliance, not on the ntpd server itself. Also, if/when IPv6 becomes more prevalent, all machines on the LAN will hopefully have a public address. You could specify a different offset based on /source/ address of the query, or on incoming interface, but I am afraid that will open yet another can of worms. -d _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
