Mikrotik Youtube Routing To Other Wan (Interface)

In this tutorial we route youtube.com to other dedicated wan link.
We need to classify the traffic through ROUTE MARKING.
There are following 4 simple steps

Step # 1 “Script”

Lot of people want to do something with connections to Google and YouTube, but they change IP addresses so often and make problems to track. One of the solutions is to dinamically update address lists on your Mikrotik router.

This script create Prefect youtube address-list

:foreach i in=[/ip dns cache find] do={
    :local bNew "true";
    :local cacheName [/ip dns cache all get $i name] ;
#    :put $cacheName;

    :if ([:find $cacheName "youtube"] != 0) do={

        :local tmpAddress [/ip dns cache get $i address] ;
# :put $tmpAddress;

# if address list is empty do not check
        :if ( [/ip firewall address-list find ] = "") do={
            :log info ("added entry: $[/ip dns cache get $i name] IP $tmpAddress");
            /ip firewall address-list add address=$tmpAddress list=youtube_dns_ips comment=$cacheName;
        } else={
            :foreach j in=[/ip firewall address-list find ] do={
                :if ( [/ip firewall address-list get $j address] = $tmpAddress ) do={
                    :set bNew "false";
                }
            }
            :if ( $bNew = "true" ) do={
                :log info ("added entry: $[/ip dns cache get $i name] IP $tmpAddress");
                /ip firewall address-list add address=$tmpAddress list=youtube_dns_ips comment=$cacheName;
            }
        }
    }
}

Step # 2 “Scheduler”
Create a Schedule to update the address-list

/system scheduler add name=youtube start-time=startup interval=0
0:00:20 on-event="/system script run youtube-script"

Step # 3 “Firewall Mangle”
Now we mark route for youtube

/ip firewall mangle add chain=prerouting protocol=tcp dst-port=80 
dst-address-list=youtube_dns_ips action=mark-routing 
new-routing-mark=youtube_route passthrough=yes

Step # 4 “Route”
Now Add Route For youtube.

/ip route add comment=”Youtube Route Traffic admsln.team@gmail.com" disabled=no distance=1 dst-address=0.0.0.0/0 gateway=197.1.1.2 routing-mark=youtube_route scope=255 target-scope=10
