I want my local ntp server up and running, so I put in /etc/rc.conf: xntpd_enable="YES" but waht are the right rules for ipfilter? Someting like: # Allow out ntp traffic pass out quick on rl0 proto tcp from any to any port = 123 flags S keep state pass out quick on rl0 proto udp from any to any port = 123 keep state Or do I have to open some ports incoming as well? [ I think I need a good book about ipfilter ;-) ] I mentioned tcp/udp because I read in /etc/services that ntp uses both. Does keep state mean that automagically all incoming traffic will be OK (for ntp) -- dick -- http://nagual.st/ -- PGP/GnuPG key: F86289CE ++ Running FreeBSD 4.11 ++ FreeBSD 5.3 + Nai tiruvantel ar vayuvantel i Valar tielyanna nu vilja
