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 
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?
