i've spent a good number of hours RTFMs, trying to make the best of a bad situtaion: userland natd instead of kernel-space nat. the only practical advice i found was to increase the maxusers kernel option - we're already at 1024 (with plenty of ram to support it). other advice was to have a streamlined ipfw list and i think mine is. the problem is that high network traffic with natd means that the CPU spends its time doing nat and not paying much attention to anything else. re-niceing it just means lower thoughput. any advice on squeezing more out of natd? * natd spawning other natds? * combinations of command line options? * more kernel parameter tweaking? thanks tariq intY has automatically scanned this email with Sophos Anti-Virus (www.inty.net) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
