View source for Different limits for Local/Overseas traffic for 3 bandwitch rates using pcq and queue tree

==1. Introdution==

Let's consider the scenario, when you want to apply different limits for many users to Local and Oversea traffic and don`t want load cpu with a lot of simple queues and you want sell for customers 3 bandwitch rates.
<pre>
1.12/6 Mbps Latvian Traffic 1Mbps/512Kbps Overseas traffic
2.6/3 Mbps Latvian Traffic 512kbps/256Kbps Overseas traffic
3.4/2 Mbps Latvian Traffic 256Kbps/128Kbps Overseas traffic
</pre>
Queue trees will limit data rate for the Local country traffic and Oversea traffic                                             
In this scenario local country is Latvia. List of all Latvian subnets located at http://www.nic.lv/local.net

==3. Explanation==

In '''/ip firewall address-list''' we created 3 lists for bandwitch profiles and list with name Latvia with latvian subnets 
In '''/ip firewall mangle''' we created address list based packet marks for bandwitch profiles.
All ips witch is not included in any address list will have second bandwitch profiles rates.
In '''/queue types''' we created pcq types for bandwitch profiles.
In '''/queue tree''' we created rules with Local/Overseas packet marks and queue types for bandwitch profiles.

Now customer with ip 192.168.0.2 have 1 profile rates, customer with ip 192.168.0.3 have 2 profile rates, 
client with ip 192.168.0.4 have 3 profile rates and all others have 2 bandwitch rates, so all traffic
will be limited and your cpu power will be free for other tasks.

===Important note===
This setup will work correctly if local network is not masqueraded. If masquerade is used then parent for all upload queues must be 'global-out' instead of 'public'. The reason for this is that pcq_upload classifier is source address. In case of masquerading source address is changed to public IP address. If queue is set to 'public' interface pcq will think that all packets are coming from one source ( public IP ). PCQ must see source address before masquerading occurs, according to packet flow diagram from manual 'global-out' is before 'src-nat'.
