Introduction

Let us consider the scenario, when you want to apply different limit to Local and Oversea traffic. Oversea traffic - traffic that doesn't belong to the Local country traffic.

To distinguish oversea traffic from Local country traffic, we will use 'mangle marks' and 'address-list' features. It will place appropriate marks to the packets to/from the Local country and Oversea networks. Local traffic is 'latvian traffic' in the particular example, list of network numbers belonging to ISPs in Latvia can be extracted from file: http://www.nic.lv/local.net

Note, 'address-list' entries should be replaced with respective addresses, if your router isn't located in Latvia. To find the actual list of network numbers belonging to your country, use Google or any other resources.

Simple queues will limit data rate for the Local country traffic and Oversea traffic.

Configuration export from the router:

/ ip firewall address-list 
add list=Latvia address=159.148.0.0/16 comment="" disabled=no 
add list=Latvia address=193.41.195.0/24 comment="" disabled=no 
add list=Latvia address=193.41.33.0/24 comment="" disabled=no 
add list=Latvia address=193.41.45.0/24 comment="" disabled=no 
add list=Latvia address=193.68.64.0/19 comment="" disabled=no
