FWIW: I just did a ping checking for MTU now that my MAXIS PPPoE is working.

So I guess MAXIS PPPoE MTU is 1464 and MSS-Clamp should be 1424 ?
I have done the traditional 1492 mtu and mss clamp 1452 without any fragmentation.
i did try to ping up to 1464 and it works. I think you might be right on that. Thank you for pointing it out.
Do enable your pppoe offload, vlan offload and ipv6 offload too(if u havent already).
Follow my ipv6 tutorial to get it running. It sped up a lot of good ipv6 based site and streaming. Eg: fb, insta, snapchat, and best of all youtube and netflix. Cheers.
