PPPoE Clients with normal LAN clients

RouterOS Beginner Basics
1

Hi there,


I currently have a Rb750 setup as a simple internet gateway and hub.


Now what i want to know is:

If i now connect a PPPoE client to that RB, will the pppoe client behave as if it was plugged into one of the ether ports with a cable?


Cause i cannot bridge a dynamic enterface?

I want to make my pppoe clients and lan clients all see each other and act as a switch

Hi,

i think no. Every PPPoE user is connecting with other via the PPPoE server.

3

So how can i “bridge” pppoe clients with network clients?

4

You can’t, which is kind of fortunate as bridging usually is a bad thing to do.

5

So i cant make my pppoe clients talk to lan clients?

not with routes or any thing?

6

Sure you can with routes. Just not bridged.

7

Oh ok sweet?

i dont care how its done as long as it works:

Can u tell me what i need to do?

Thanks

It’s routing. If the following conditions are met:

  • the two devices are not on overlapping IP address space
  • all routers between the two devices have routes to the respective IP addresses of the two devices (could just be one router they both are connected to)
  • no firewall between the two devices is dropping traffic
  • the two devices are forwarding traffic to a router if it isn’t destined to their local subnet

then traffic will be routed between the two.

So in my case:

I wil want them to both be on the same IP range just there must be no duplicates?

then i go to routes and i say destination 192.168.1.0 ether1?

And it should work?

Are the LAN clients and PPPoE clients connecting to the same router?

If yes, it will just route traffic between them out of the box. It has directly connected routes, after all.

11

Yes they are:

one router, plugged into modem and switch ( all pc connect to the one switch and then intern the same router)

So u say it will just work?

12

Yes.
It would probably be a good idea to read up on how TCP/IP works.

13

I would echo that you should try to do this with routing, but in the PPPoE profiles, you will see that you can in fact add the PPPoE interface to a bridge dynamically (not that you should, usually).

One of PPPoE’s features, unless you’re only using it for authorization, is to create an isolated point-to-point link.

Oh yes,

I remeber seeing that now.,
Thanks so much,

I dont really mind if u not meant to do it. its for home. as long as it works im happy.


Thanks i will give it a try.
