PPPoE auth on CPE but let IP pass to client?

RouterOS General
1

I have this chain of connectivity

rb1200(A)(userman) > rb1200(B)(pppoe-server radius to B) > rb411 + sector > SXT CPE > client router

This all works if the SXT is the pppoe client and gets the IP address assigned in userman.

What I am wanting to do is have the SXT do the pppoe auth, and then bridge the pppoe-client interface to the ETH0 interface and let the client’s router statically assign the IP address without doing PPPoE.

I have a couple of sites using QWEST/CentryLink DSL with a motorola DSL modem that is able to do this. Is this an option for me on mikrotik?

Thanks

No bridge needed. You can create a PPPoE client on wlan interface which get Dynamic IP form PPPoE server. Then in Eth of SXT add static IP address. You can also run DHCP server on Eth interface which assign IP to your client

don’t forget to add

/ip firewall nat add chain=srcnat action=masquerade out-interface="PPPoE-client"

I’m a little confused.

if my public IP address that is assigned to the pppoe-client on WLAN is 20.1.1.25
what IP do I assign to the ETH interface?
what IP can the CLIENT’s router get?
where does the NAT come into play?
