PPPoE Server on different network

[Need Advice]
Hi Guys, i need an advice for networking problem…
me and my friend recently accepted for internship in some company

they want us to ‘remake’ their network because all of their connection is in 1 Network only…(and now almost run out the available IP)
so they want us to do segmentation to their network… and in no time they already get us new Router (Router CCR) to replace the old switch backbone..

the requirement they asking for is to have PPPoE so client on LAN have 2 IP, 1 for Local and 1 for Internet Connection..

and for now we just try to have simulation with 2 MikroTik RB750

The problem is… while we doing PPPoE… we can only make it works if the PPPoE client is on the ether/port that PPPoE Server had been configure. if we add a Router to make the segmentation(Network A/B/C) in Router B, the client can’t get the IP From PPPoE Server from Router A, so in theory we need something that redirect request in router B to router A’s PPPoE.

How can we config the ‘redirect’ thing to Router A?

*note : we accept another solution or advice for this topology, actually their main problem is want to replace the Switch Backbone->Router CCR MikroTik, and their IP is running out.

Sorry for the bad english i’m just some college student’s that still have a lot to learn :slight_smile:

Hi,

You’d have to bridge the interfaces that require PPPoE so the discovery packets are passed along, so for instance if on your CCR you have

ether1 - to RouterA
ether2 - to Switch1
ether3 - to Switch2
ether4 - to Switch3

Set up a bridge interface containing ether1,2,3,4 (or use the switch chip if your model of CCR has switch chip)

Then on Router A broadcast PPPoE server on the interface that goes to the CCR.

thanks for the reply…

yesterday we got some idea about doing PPPoE on each port on Router CCR that goes to switch, so Router A only got firewall Rule and Proxy Server because the Internet Connection is attached to that Router how about it… can i ask what the +/- on each plan?
