Important: Move this rule above of other PCC rules, so it will accept the data before PCC catches it.
=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x=x
To Exempt Any User IP from PCC Rule,
/ip firewall address-list
add list=usere-exempted-from-pcc address=172.16.0.2/32
Now create Mangle Rule to accept traffic from above list, then PCC will not precess this user ip address , and Mikrotik will use the Default route for this user Traffic. (We will add it later)


Example:
/ip firewall mangle
add action=accept chain=prerouting disabled=no src-address-list=user-exempted-from-pcc



Adding Route for Un-Marked Traffic
You have to add Default ROUTE rule to tell Mikrotik to use this ROUTE as default route for all other UNMARKED traffic not processed / marked by the PCC. and in this route, you can bind exempted traffic request to always go through Specific Link only.
/ip route
add comment=”Default Route For Un-Marked Traffic” disabled=no distance=3 dst-address=0.0.0.0/0 gateway=101.11.11.36 scope=30 target-scope=10


HOW CAN I ADD WAN1 PACKETS MARKED BY PCC. WHAT IS SCRIPT FOR THAT.

I will definitely try to use it but i did not understand about the ppc address please specify more.
