Mikrotik IP and External Server IP out of Queue

Hello, I would like to know if you can make network users access a hotspot page without a speed limit, or for example, 50M.
And also by scripts and external hotspot I would like to make a given IP: ex: 54.2.22.1 to be accessed not go through the control.
Get a 30k limit for whatsapp only, and no access points released from the Gardened Wall ips list * .whatsapp *. Only that the mikrotik insists on controlling a band of access to the page of the hotspot and to the external server.
Can someone show me the way.
Sorry for my english.
My hotspot network: 10.22.50.0/22
Ip of hotspot : 10.22.50.1
External ip: xx.xxx.xx.xx (ex 54.2.22.1).
