(ie they are piggin up the > wire) You might need to add a buffer to the pipe config; I don't know if the default pipe setup has an infinite buffer or not. Try adding "queue 100 packets" to each pipe config line. You can see how much data is going into the pipe with "ipfw show". take two samples, 10 seconds apart, to see how much traffic is trying to get through. "ipfw pipe show" will list each pipe, plus how many packets are queued up, and how many packets were dropped. -- Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
