PPPoE Relay help


i need to use a pppoe relay on my lede router vdsl to attach another router that has a configured VoIP service. This VoIP service is configured to do a personal connection to my isp using a pppoe, so i need to make the lede router to do the pppoe relay service.

I tried installig relayd, creating a new relay interface between lan and ptm interfaces, but a simple connection using my pc windows pppoe-passthrough always does an error.

i'm sure i'm making something wrong, can you help me?

The issue was resolved? I ask will share!
Thank you!
