28 2 * * * /usr/sbin/ntpdate -u -s time.nrc.ca in cron, (using udp request). DNS is round robin balanced between two hosts, see below. In /etc/ipf.conf: pass out quick on ex0 proto udp from your.ip.goes.here to 132.246.168.164 port = 123 pass out quick on ex0 proto udp from your.ip.goes.here to 132.246.168.148 port = 123 pass in quick on ex0 proto udp from 132.246.168.164 to your.ip.goes.here port > 1023 pass in quick on ex0 proto udp from 132.246.168.148 to 24.215.16.38 port > 1023 --Stef [EMAIL PROTECTED] ----- Original Message ----- From: "dave" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Sunday, July 06, 2003 4:51 PM Subject: allowing news out > Hello, > I've got an ipfilter firewall that i'm tightening down.
