Also, “ipfw delete 1″ does not delete the pipe, it deletes rule/s #1. To delete the pipe numbered 1, you need to do:
ipfw pipe 1 delete

To list the rules:
ipfw list

To list the pipes:
ipfw pipe list

@Ignacio: that ’25′ is the TCP port number, in this case for an SMTP server.

@OP:
There is a mistake in this line:
sudo ipfw pipe 1 tcp from me to smtp.west.cox.net 25
it should be
sudo ipfw add 1 pipe 1 tcp from me to smtp.west.cox.net 25
(i.e. you forgot the “add ” in the example)

I’ve been using this throttling for years, but for some unexplained reason this throttling has stopped working for me in recent months. I am running Snow Leopard 10.6.8 presently, I think one of the updates in the past months broke this for me…

A question… What is the meaning of the 25 at the end of the second command?
