Let's consider shaping of traffic that comes from internal network. I can do this using pipe for outgoing traffic on external interface # ipfw add pipe 1 ip from 172.16.0.1 to any out via $ext_if or for incoming traffic on internal interface # ipfw add pipe 1 ip from 172.16.0.1 to any in via $int_if Is there any practical difference between these rules? I've read ipfw(8) manual but didn't found anything about pipe implementation. It's a token bucket, right?
