Hello everyone, I sent this out a couple of days ago, but I don't think it actually got out. Anyway, my little network here consists of a wireless router branched off of my FreeBSD box, which routes for all of the cabled computers in the house. There are two wireless clients, laptops, that are in use constantly and between the bit torrents and viruses it's either chewing up my upstream (the achilles heel of my cable connection), or generating some unwholesome amount of packets, or both. I've tried setting up dummynet pipes to restrict the bandwidth for 10.0.0.8 (that's the ip for the wireless router's cabled side), but that dosen't seem to be working. Here are the rules I've been trying, let me know if this not correct: ipfw pipe 1 config bw 50Kbit/s queue 10 delay 2000ms #outbound ipfw pipe 2 config bw 150Kbit/s queue 10 delay 2000ms #inbound ipfw add deny icmp from any to any ipfw add pipe 1 all from 10.0.0.8 to any ipfw add pipe 2 all from any to 10.0.0.8 The painful delay was to test if the pipes were actually working, but never seemed to make a difference. I even tried assigning them to 10.0.0.0/24, but also to no effect. Dummynet is enabled in the kernel, HZ is set to 1000, and passing these dosen't generate any errors, so I have no idea what's going on. Am I just not following how this works? Last question for now, can these pipes also be used to numerically limit packets, or am I limited to slots and memory sizes? Thanks!
