Using ESP32 as PPPOE server possible?

[Smig0l]

Hi! I have come across your project after reading Wiznet W5500 pppoe docs...
I have an ESP32 and a W5500 lite module.
Is it possible to create a PPPOE server?

I know that this project is 8 years old but wondering if u can help me.

Technically perfectly possible.

But there might better Ethernet options for ESP32 than W5500:
eg something like this https://www.olimex.com/Products/IoT/ESP32/ESP32-GATEWAY/

Looking at RFC2516, it looks like you need to process these EtherTypes:

• 0x8863 (Discovery Stage)
• 0x8864 (PPP Session Stage)

But then you either need to implement PPPoE yourself or glue in an existing library.
And then I guess route the IP packets over normal Ethernet?

I did have some success with implementing PPP for IPv6:

the only library i could find that mentions pppoe is this.

but it says "PPPOE_SERVER is not yet supported under lwIP!" even if i see some server function (like pppoe_send_pado)...
