PPPoE Server - Bridge with other interface

RouterOS Beginner Basics
1

Hi there,

i have the following setup:

Router 1: WAN with Public IP
LAN 192.168.0.1/24

I want to create a PPPoE Server with the following interfaces:
Eth1: Connection to Router 1
Eth2: PPPoE Server

The PPPoE server should give static ip-adresses to the clients. For example client1 192.168.0.101 and should be bridged to eth1 if connected.

Does anyone know, how to configure the mikrotik for such a purpose?
I am struggling with giving routes to clients and how to bridge with another interface.

Thank you for your help

I consider ditch mikrotik

Me neither,
Its an easy connection to the primary router via a static IP address.
Just need to set ether1 as a WAN interface and give it an IP address.

The pPPOE server aspect is specific to the router and how it handles PPPOE addressing to clients.

I really need to assign ether1 of the PPPoE router an ip-address? Just bridging would not work?

Why would you bridge, I dont understand the purpose of doing that.
Thee pppoe server is your router, not the ISPs router??

Caveat, I am no pppoe expert so maybe there is some requirement not aware of?

You cannot bridge PPPoE to another interface as the client-server connection is IP / layer 3, not ethernet / layer 2.

To communicate with Router1 your PPPoE server ether1 requires an IP address, and you can use proxy ARP so the Mikrotik answers ARP requests for any PPPoE client addresses overlapping with the 192.168.0.0/24 subnet.

Thank you, proxy-arp was the solution.

My config now looks like the following:

/interface ethernet
set [ find default-name=ether3 ] arp=proxy-arp
/interface wireless security-profiles
set [ find default=yes ] supplicant-identity=MikroTik
/port
set 0 name=serial0
/ppp profile
add bridge-learning=no dns-server=8.8.8.8 name=TestProfile1 use-compression=no use-encryption=no use-ipv6=no use-mpls=no use-upnp=no
/interface pppoe-server server
add authentication=mschap2 default-profile=TestProfile1 disabled=no interface=ether2 service-name=PPPServer
/ip address
add address=80.80.80.249/28 interface=ether3 network=80.80.80.240
/ip route
add disabled=no distance=1 dst-address=0.0.0.0/0 gateway=80.80.80.41 pref-src="" routing-table=main scope=30 suppress-hw-offload=no target-scope=10
/ppp secret
add local-address=80.80.80.249 name=User1 profile=TestProfile1 remote-address=80.80.80.246 service=pppoe

Encryption really slows down the hEX S. Any recommendation in tuning the configuration?
I am not sure what to set at “local-address” in “/ppp secret”, but it is working. I am insecure, because it is the same ip at ether3.

Setting the local interface to the same address as that on any other interface is fine. Encryption on PPPoE is probably unnecessary if you are extending internet access to others as the WAN link to the internet isn’t secure, clients will be using TLS to provide end-to-end encryption.
