Yes, that looks right, still, that case probably doesn't perform all that well at all and could be improved. > The select is there currently mostly to get information from routing > socket which is needed on DHCP / PPP environments.

I guess then it looks like natd really either wants batch-recvfrom/sendto or to be moved into the kernel for higher performance. -- -Alfred Perlstein [[EMAIL PROTECTED]] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-net" in the body of the message
