As here is no userland processes involved: PPPoE is porcessed by netgrpah, routing & ipfw is kernel stuff too...

Also, I noticed, that with any scheduler it could not route 40Mbit in BOTH directions simultaneously, and downstream has priority. When there is no much of downstream, it upload at 40-45Mibt/s, and when downstream is 40-45Mibt/s upstream could be only about 20Mbit/s. -- // Black Lion AKA Lev Serebryakov <l...@freebsd.org> _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
