Hi all, After a long reading of the LARTC, I were able to set up a working HTB config on my firewall. But my question is : Can I use a "ip less" box to do QoS ? With bridging software (or even without?) or thing like this and use an u32 filter to direct the traffic to the right class ? In other words, I can't modify the existing network config or inster into (netmask is 255.255.255.252) and I want to shape traffic before the router. (And the firewall can't do bandwitdth managment...) Many thanks in advance and happy new year 2003 ! G.
