Hmmm ... you realize that ALTQ takes *BIT* per second? > Is it a good idea to check the behavior of the ruleset with OpenBSD? First of all a look at your queue statistics would be helpful: $ pfctl -vvsq how many packets are being dropped? Which queues do the packets end up in? If you can easily check OpenBSD behavior, that'd be a good check as well. -- /"\ Best regards, | mlaier_at_freebsd.org \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | mlaier_at_EFnet / \ ASCII Ribbon Campaign | Against HTML Mail and News
