PPPoE Server Raspberry

Hello everyone!

This is my first post in the forum and I would appreciate if you can help me.
I have installed Openwrt (corresponding image) on a Raspberry pi 3 B and the PPPoE Server module as I need to test. For this I have connected the eth0 interface integrated in the board with a LAN port of my router and the eth1 interface (Ethernet USB) to the port of my laptop. (eth0 = br-lan)
I have created a vlan 20 on interface eth1 = eth1.20.
IP range 10.0.0.0/24 and I am listening on the PPPoE server 10.0.0.1.
I try to make a call from m'y laptop with the corresponding user and password and there is no way that it works.
Do I have to adjust something in the routing or something else that escapes me?

Thanks

A couple of ideas. When something doesn't work try breaking it into simpler parts. No, put down that hammer, I meant with your configuration.

Try and connect without the PPPoE and see if that works. Try connecting with SSH and try pinging outside of the Raspberry Pi. Try it without the VLAN configuration. Are there any errors in the OpenWRT logs?

Thks Wayne1234 for the proposed ideas.
I created an interface without VLAN (eth1) and I plugged cable to my Laptop Ethernet port. After that, I tried to connect by PPPoE with result "No PPPoE Server found" but curiously in the part of the script below you can see that it assigns an ip of the range defined on the server

I don't know much about pppoe-server but it is essential to present here the configuration you have added/changed. Also it would be useful to run all the tests with firewall disabled until you verify that it works. One more thing to watch out is that OpenWrt is case sensitive, so be careful when you use the WAN instead of wan.
