ER605 PPPoE Static IP Secondary Connection Issue

Hi,
My ISP provide 2 static IP over PPPoE connection. I try to setup secondary connection with fixed IP provide by ISP but seems failed. I can see there was a log:
"PPPOE failed to connect to the server because authentication failed with the wrong username or password."
But when revert back the secondary connection to "none", the PPPoE connection work fined without issue without changing username & password credential.
I try secondary PPPoE on Mikrotik and Home TP-Link product, the secondary IP work fined with same PPPoE username and password.
I already contact my ISP, they inform that PPPoE gateway should support "IP Unnumber Configuration" or gateway should support additional multiple IP in WAN configuration in order to use static IP. I don't know whether ER605 or other Omada Router product able to support this function.
Diagram below I replace D-Link gateway with ER605 and success to get secondary public IP from ISP
So both Mikrotik and D-Link able to support "IP Unnumber Configuration". Maybe I need to raise this feature to TP-Link.
I just find how to configure secondary IP and already success, but still no function as one-to-one NAT did not work on PPPoE. I test on PPPoE account with 1 static as below.
But it is weird because secondary IP, I need to set subnet mask as /31 to make the PPPoE dialer success. Secondary Connection subnet mask cannot be set to /32 or /30 for 1 static IP. Later I try on 5 static IP PPPoE.
But still, useless as one-to-one NAT unable to config
