Limitar el ancho de banda en OSX (recomendable para internet compartido a través de modem móvil)

limit_band_width.markdown

Let’s assume we want to simulate a 8 KByte/sec limit for port 80

####Step 1 – Define bandwidth rule

sudo ipfw pipe 1 config bw 8KByte/s

####Step 2 – Bind rule to port

sudo ipfw add 1 pipe 1 src-port 80

Now we have added the rule 1 and the limit should be active.

####Remove bandwith limit

If you want to disable this limitation again fire up terminal again and delete rule 1

sudo ipfw delete 1
