Feature request: PPPoE 1500 MTU support (RFC4638)
Region : Australia
Model : TL-ER6020
Hardware Version : V1
Firmware Version : 140604
ISP : n/a
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.
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.
