Routing without NAT...

Hello all,
I am newbie to the mikrotik routing.

I want to route through mikrotik without nat. Can I accomplish it?

I am currently connecting to my ISP via PPPoE.
Also,
I am providing my users via PPPoE server.

Due to two PPPoE connections, I am facing double NAT in my network.

If there is an anyway to route via mikrotik without nat. The it would be easy.

My confuguration:
WAN: Gets public IP via PPPoE
IP Pool for PPPoE: 10.57.32.0/20

Also, my users use TP-LINK router which has in-build NAT. It doesn’t support bridge mode.

Yes. Routing without nat is the main feature of router.

How to accomplish that?
Can you please send me the codes.
