In this case you may need to remove the rule before you remove the pipe because of the dependency between them. 1) ipfw pipe flush 2) ipfw flush 3) ipfw pipe flush 1) Pipe 1 still has a dependency. So you should be only able to remove pipe 2, as this isn't connected to anything 2) This will remove all rules, thus removing the connections between all pipes. 3) This will remove any remaining pipes. This could also be done at 2 if ipfw remembers you want to remove the pipes. I didn't try this out, it just seem logical to me this way. I hope this is any help. -- Best regards, Alex mailto:freebsd@akruijff.dds.nl To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ipfw" in the body of the message
