RT-AX88U PPPoE WAN error

[Grufffler]

My ISP in the UK ships Huawei HG8245Q2 devices - too many reasons to individually list why, but I want to replace this - preferably with my RT-AX88U (running Merlin 384.14_0). Where live it's single service provider area, and the ISP is very small, and simply doesn't have the resources to support people using their own devices, so won't give out any configuration info willingly.

Nevertheless I've managed to gain root access to the Huawei device and pull an unencrypted version of the configuration file. I've got my own ONU to connect the fibre to, and configured this to work the Huawei OLT on the ISP end. Now having issues with PPPoE configuration (I think).

It appears to be failing PAP authentication, with errors from pppd:

The remote system is required to authenticate itself
but I couldn't find any suitable secret (password) for it to use to do so.

My question is how can I debug this? I see someone else was seemingly able to get a capture on the WAN interface to view PPPoE negotiation (Here: Asus RT-AC88U - PPPoE WAN Connection problem ) how can I do the same? Or would I need something like a physical network tap?

Apologies in advance if this a silly question - I'm probably not searching for the right terms on the forum

you need to put in a username and password that your isp gave you for pppoe

Yup, that’s in already. Extracted the username and login from the Huawei router

I did the same with a rt ac 88 u in my case apart from the username and password I had set my vlan to 2 and prio to 0 . Most ISPs have a community help forum and that's how I found my settings. I'm in Australia though and TPG is a rather large ISP

Thanks - yeah double checked the VLANs and priority to match that of the Huawei. Still no such luck.

Any ideas on debugging this traffic traversing the WAN interface?

No sorry but if it were me I would nag the hell out of the ISP to the point of suggesting that if you can't get it to work you may need to take your business elsewhere until they put you onto a technician who can help
