I have a Mikrotik router,and also i have a wireless network for distribution. and as you know we configure every PC/laptop/ … in order to connect to the server through PPPoE. But now when i have for example a cafe shop and i need to connect a router ADSL to the server through PPPoE in order to enable every customer/user to connect without need to configure the device and insert user name and password.
Can we configure the router and connect it through PPPoE to server and distribute Internet for everyone.? if yes how we can do that?
Either NAT on the PPPoE client router so that to the server it appears that there is only the client and no devices behind it (not ideal since the PPPoE server will NAT again, this may break some protocols but will work sufficiently for web browsing), or ensure that the PPPoE server has a route to the network behind the PPPoE client router. If you use RADIUs for authentication that can be done via the Framed-Router attribute, or you can just make sure the client router gets a static address and you implement a static route on the server.
