Consider this scenario.
- a mikrotik router with network segments (office1, office2, office3, wireless,…)
- every segments have a hotspot active
- between segments there aren’t hotspot (a simple ip wallen garden rule permit this)
- every segments have a simple queue to limit bandwidth for the specific segment
Now I wanna a better result 
Some segments (for example office3) have a lot of repetitive and massive downloads (for example the same large file used from 20-30 clients).
A proxy will be natural choice. But I want a full trasparent proxy that don’t change the bandwidth that every segment consume.
What is your suggest?
