PPPoE Setup for WISP

Hi all,

I have this scenario where I want to setup a PPPoE Server.

Mikrotik CCR as Gateway → airfiber24 (bridge) → RB1100Ahx2 → (I have 172.18.x.0/24 for every net) Mikrotik RB (850gx2) → Ubiquiti Access Point → Ubiquiti CPE → Mikrotik CPE Router

Now I want to setup PPPoE, is better to setup a PPPoE server on the CCR Gateway, or one for each subnet on RB 850Gx2?

Can you tell me how to do this? If I want to propagate public ip how is it possibile with PPPoE?

Thank you!

you can have userman on your core router, and have every user there in place with their package.
