Sophos XG PPPOE passthrough

Yung Chang

Did Sophos can set PPOE passthrough? I have six dynamic ip and one fixed ip. I want to use the six ip for my cilent, but don't know how to make this work. Is there someone could help me with that?

Thanks.

    Hey Yung, Welcome to Sophos Community.

    Are you talking about passing PPPoE to a downstream device (Passthrough) and dial it from there? 

    Or is it where you want the fixed IP on XG and configure dynamic IPs on downstream machines?

    Thanks for reply.

    I want dial from downstream device and XG let PPPoE connection from downstream device could passthrough to the ISP modem.

    Hey there Yung, 

    I have tested this with my PPPoE Connection by dialing PPPoE in a laptop connected behind XG and it works. However, I wasn't able to access the internet but PPPoE dial was successful and the device was getting the public IP and DNS information from ISP (Could be something on ISP end).

    You'll have to configure a Bridge Interface with two ports, One where the Upstream ISP device connects and the second one where you connect the downstream device. Don't configure any IP address on the bridge.

    Just a note, It's not ideal to configure PPPoE this way, rather you should connect the ISP device directly right where you dial PPPoE.
