Firewall Mangle

How can i bandwidth only 512kpbs all packet that access to this ip !118.67.200.0/21 ??? :smiley:

hi.
you must mark packet in ip firewall mangle with your ip address(!118.67.200.0/21),and then set queues with 512k and select routing mark that you create.

could you show the the working code for mark the packet?
