Trying to configure Mikrotik to use existing DHCP Server for PPPOE

I’m currently trying to properly setup a PPPOE Server using an already existing DHCP server, I’ve tried to search on forums but not getting the results I need.

I’ve gone thru the tutorials but they all used the Mikrotik itself for dhcp and a IP range that doesn’t match, I’ve even watch about 7 didffernt youtube videos with no luck. The best I could do was get a router to connect to the PPPOE server but it could never get on the internet.

Internal Setup

DHCP Server 192.168.1.1

SUBNET 255.255.252.0

DNS 192.168.1.1

wins 192.168.1.1

I would like the PPPoE Service to pull from my internal DHCP server, I was testing with a pool of, 192.168.2.1-192.168.2.250 I can get the client to connect and get a IP but it cant access the internet.

If anyone could point me into the right direction I would appreciate it.

Detailed configuration example,

PPPoE uses own addresses from /ip pool, moreover for better security local interface (PPPoE server is configuration) should be without any IP address.

Otherwise anyone can put static IP address, correct gateway and get access to the network without authorisation.
