All,

CVSUP from 1/16, running natd with command /sbin/natd -config =
/etc/natd.conf -n dc0. Config file is:

log_denied
log_facility security
use_sockets
same_ports=20
unregistered_only
redirect_port tcp x.x.x.x:80 x.x.x.x:80
redirect_port tcp x.x.x.x:443 x.x.x.x:443
redirect_port tcp x.x.x.x:8880 x.x.x.x:8880
redirect_port tcp x.x.x.x:2953 x.x.x.x:2953
redirect_port tcp x.x.x.x:2954 x.x.x.x:2954
dynamic
punch_fw 10000:1000

I'm going to try removing the log options and see if it improves. but =
since this is a new issue with the recent cvs build, I did want to send =
out a query.

What I'm seeing is natd going to well over 90% cpu on this box, which =
has never happened before to the best of my knowledge. What tcpdump is =
showing my is very large amounts of arp traffic on the external =
interface from a large part of the 12.237/16 network (yeah, I know, lame =
provider). Has anyone else been running into similar issues?
