Hello, does anyone have a working solution for the shaping both incoming and outgoing traffic in such way, that for a given client the *sum* of incoming and outgoing traffic is somehow defined? My ISP does the same thing, it gives me just a line of a defined rate, no matter the traffic direction (i.e. here is your line, the clock speed is 1024kbps, do what you want). I''m a litte bit familiar with HTB, my download shaping works fine. However, I would like shape both incoming+outgoing traffic in a way that the sum of actual outgoing and incoming rates of all my clients would be always below the ISP''s line speed in order to shaping get working. In other words, I would like to split the ISP''s line into a bunch of hierarchical "virtual" lines with traffic borrowing etc. like HTB does for download, but with defined *total* rates (i.e. dear customer, here is your 128kbps line, do what you want). What can I do with HTB is to shape incoming and traffic separately (somehow to virtually split the line for upload/download with limited speeds), but this is not the way I would like it to be, since would like to get the line used as effective as possible. Maybe something like IMQ would work, but unfortunately I have found no example for that solution. Any ideas?

It works but I didn''t prioritise empty acks so testing both ways with TCP will fall apart - but then it does on a full duplex connection. Remember it''s a test and I can''t even remember the detail so you will need to modify alot - INPUT/OUTPUT etc for real world.
