General • After configuring PCC load balancing, the required DDNS public IP address cannot be obtained.

My family currently uses two broadband service access providers. IPS1 provides a Dynamic public IP address, and IPS2 does not provide a public IP address. When I use the IPS1 service provider line alone, the router can obtain the correct public IP address and can use the DDNS service normally.

The problem now is: I use both IPS1 and IPS2 lines. PPC load balancing is configured for them. The public IP address obtained by DDNS is IPS2 (the IP actually obtained by the router is the intranet IP provided by the IPS2 service provider)

The help I need is:
When I use two lines, DDNS specifies to obtain the public IP address of IPS1.

This is my first time using MikroTik routing products. I followed the official video tutorial to do PCC load balancing. Due to the language, I could only configure it based on my own understanding. I don't know if the configuration is correct (but the actual effect is very good). I'm attaching my own configuration parameters, hoping to help.

Hardware: RB5009UG+S+
Software version: 7.13.3 stable version
IPS1 service provider: The access speed is 1000M downlink
IPS2 service provider: access speed is 500M downlink

I made 3 routing connection tags: IPS1_conn, IPS2_conn, IPS3_conn，1 and 2 are marks for the IPS1 service provider, and 3 is the mark for the IPS2 service provider.

Configuration screenshots are below
