CCR1036 + SFP DFP-34X-2C2. How to dial secord PPPOE or Dial PPPOE by another Eth port

I am currently using CCR1036 + SFP DFP-34X-2C2. I have created a VLAN 1226 for dialing PPPOE and it works fine. How can I allow other ETH Port devices to dial PPPOE at the same time (EX: I connect a PC to Eth-10 and use this PC to dial PPPOE)? I tried to create a Bridge or VLAN to connect SPF and ETH10 together, but it doesn’t seem to work. I’m not sure if this function cannot be achieved or my settings are incorrect?
In addition, when my CCR1036 is connected to the Modem. provided by the ISP, I can successfully dial more than 2 PPPOEs at the same time, but using SFP DFP-34X-2C2 can only dial one. What is the reason?

SFP DFP-34X-2C2:V1.0-220923
