traffic shaping

hi list, I'm planning to configure our firewall with traffic shaping. I'm using SuSEFirewall2. I'm looking for a way to devide my bandwith between two nets. the intranet should only get a small part of the total bandwith, so the rest will be used by our extranet. So if anyone understands what I mean.... ;o ) : Is there a tool for traffic shaping ? I've heart of a package that comes with SuSE, which does traffic shaping, but I can't remember it's name. Please note, that I don't wanna use squid for traffic shaping but the firewall. thanks for your help maX Bauer
