[ale] Throttling traffic on firewall

I found the docs you recommended and have looked at the Bandwidth
Limiting HowTo as well.  Thanks!

I wonder about setting up a test for this.  I have a small network at
home I can use.  I plan to start a large FTP transfer but would like to
test using other protocols.  Is there a tool that simulates passing a
predetermined number of packets from many/all protocols and services? 
Let's say I want 1 Gb of HTTP data, 1 Gb of FTP, 1000 ICMP pings, 1Gb of
SSH "scp" transfer data, and so on.  Any single tool or suite that does
something like that?  I can always manually set this up is several
shells and then hit the go button, but sometimes a single tool is nice
to have.  

I am trying to limit outgoing bandwidth on the outside interface of the
firewall to 1.5Mbit/sec and shape the traffic that is going both ways. 
I don't think I have to limit per se the incoming bandwidth but would
like to guarantee bandwidth to admin services.  So the iproute2 package
is perfect and combining with Squid is great for shaping based on domain
name.
Thanks,
Dow

The online documents I have found so far are a bit sparse and confusing to me.  Has anyone any experience with limiting a large pipe and controlling bandwidth based on domain name or IP?  Thanks,
