thanks for quickly answer Corey

Just another question related w/ shapping  

at some documents it's describe the use of IMQ and some other the use of
dummy device. What's the best method ? From what I've read we use dummy
to shape both lan and wan using dummy device. It's correct? If it's
correct why does we use dummy insted shape at LAn and Wan Interfaces ?

I intend use TC + iptables + debian sarge, but I'm not sure about using
dummy device....


thanks in advance
