Bandwith limits for zone "blue"

Hi all,

is there an easy way to limit the bandwith for the whole zone “blue” to/from the internet for example?

My first attempts were with QoS, but i get no good result…

Thanks,
Volker

Not sure if there exist more established/standard methods for doing this. But you should be able to apply rate limiting rules using iptables to your BLUE zone. I found this decent article/tutorial after a quick search.
