I heard that matching ports with mangle and shape with CBQ or HTB will cost me some resources so i want to limit that way :

 

1. On forward I want to limit a port range like 0 to 79 at 8kbps .And after that i want to be able to add lines with other port range , also at 8kbps, but only on forward .Today i had just started to use BBQ and HTB
