I've been working on a way to keep my outbound NNTP traffic from interfering with all other traffic. After reading the ipfw(8) man page and several other resources (including Luigi Rizzo's page), I thought I had it down: ### Outbound ipfw pipe 1 config bw 0K ipfw queue 1 config weight 1 pipe 1 ipfw queue 2 config weight 100 pipe 1 ipfw add 1000 queue 1 all from any to any out dst-port 119 via fxp0 ipfw add 1001 queue 2 all from any to any out via fxp0 ### Inbound ipfw pipe 2 config bw 0K ipfw queue 3 config weight 1 pipe 2 ipfw queue 4 config weight 100 pipe 2 ipfw add 1000 queue 3 all from [NNTP server IP] to any in via fxp0 ipfw add 1001 queue 4 all from any to any in via fxp0 My thinking here is that both queues (in each direction) will share all available bandwidth, but any traffic heading out on port 119 or returning from the news serverwill be superseded by all other traffic. If there's no other traffic, NNTP will be able to use all available bandwidth. It would appear I'm not grasping the concepts. Can anyone tell me what I'm doing wrong? Thanks, Brad Waite
