Hi,

How to tuning natd ?
My natd have 90% CPU usage;-(

natd.conf is
use_sockets yes
same_ports yes
unregistered_only
interface fxp0
punch_fw 2000:50

mapped 1000 private users.

curretly sysclt is :
kern.polling.enable=1
net.inet.tcp.blackhole=2
net.inet.udp.blackhole=1

net.inet.tcp.recvspace=65535
net.inet.tcp.sendspace=65535
kern.ipc.maxsockbuf=4388608
net.inet.tcp.rfc1323=1
net.inet.ip.fw.dyn_max=8192
net.inet.tcp.keepidle=10000
net.inet.tcp.keepintvl=7500
kern.ipc.somaxconn=65535
net.inet.ipf.fr_tcpidletimeout=7200
net.inet.ipf.fr_tcpclosewait=120
net.inet.ipf.fr_tcplastack=120
net.inet.ipf.fr_tcptimeout=240
net.inet.ipf.fr_tcpclosed=60
net.inet.ipf.fr_tcphalfclosed=300

any modification? or other (kernel/natd) optimization?

thanks
