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?
