It certainly looks like it could use some cleaning.. It's suffering from 'evolutionary changes'. We at whistle have to take a lot of the blame. We implemented 'divert' sockets after a suggestion from one of the CSRG guys. (forget his name.. the Kieth that was not a Bostic) The divert functionality adds a lot of possibilities but it has its tentacles all over the place. The 'fwd' option of ipfw has a few tentacles reaching as far as tcp_input. The dummynet stuff I can't comment on so much.. julian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
