Hi,

I'm disappointed to see that this high-end router does not support setting the MTU of the WAN ethernet interface above 1500 and the PPPoE MTU to 1500. My ISP supports this but the ER-6020 does not.

You heard any router could do this?

I know not many routers support this. I'd at least like an acknowledgement of my question from TP-Link with either an ETA of the firmware support or a technical explaination why it can't be done (eg. underlying firmware simply can not exceed 1500 MTU for the ethernet interface without major changes)

Did you try to google it? I am not a technician but I know that PPPoE protocol specifies the maximum MTU to be1492 bytes and PPPoA protocol specifies the maximum MTU to be 1500 bytes.

Hi,

I support this request.

RFC4638 is now several years old, and major open-source implementations like mpd5 on FreeBSD as well as several devices to what TP-Link sells like the Draytek Vigor 130 support this in both bridged and routed mode.
