From dummynet(4): ipfw pipe 1 config bw 1Mbit/s ipfw add pipe 1 ip from A to B out ipfw add pipe 1 ip from B to A in where A can be one of the following (from ipfw(8)): ipno An IP number of the form 1.2.3.4. Only this exact IP number will match the rule. ipno/bits An IP number with a mask width of the form 1.2.3.4/24. In this case all IP numbers from 1.2.3.0 to 1.2.3.255 will match. ipno:mask An IP number with a mask of the form 1.2.3.4:255.255.240.0. In this case all IP numbers from 1.2.0.0 to 1.2.15.255 will match. You can also add ports to that in the same way you would make a normal filewall rule. -sc -- Sean Chittenden To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ipfw" in the body of the message
