pppoe problem

Hello,

The MTU error is misleading since PPPoE only supports up to 1492 bytes. This error has been removed from newer versions of software. If you are still running version 2.0.2, you may want to consider upgrading your devices. We have published an article in the Knowledge Base on troubleshooting PPPoE issues:
