"PPPoE Relay" feature in a router
« on: November 25, 2016, 03:52:56 AM »

I've just got hold of a Solwise 4G router (model 4G-54rv) and Iíve noticed this has an option to enable something called "PPPoE relay". Any idea what this might be?

Could this simply be a feature to turn the router into a straight PPPoE-speaking modem? (Yes, I know, just try it. But I'd rather not risk simply locking myself out for no good reason. I have backed up all the config so if I have to reset it to regain control then I can do so without losing all my work.)

I just wondered if anyone had seen this terminology used elsewhere in routers.

That is a phrase which is new to me. So I did a quick search . . .

It seems to be something like --

PPPoE Relay: Enable PPPoE relay allows devices in LAN to establish a individual PPPoE connections that passes through NAT.

Here are the first two links from my search --

http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/bbdsl/configuration/xe-3s/bba-xe-3s-book/bba-relaydis-ssf-xe.html

And finally the link to a Cisco PDF file --

It doesn't sound as if this is going to turn the router into a mere straight PPPoE-speaking _modem_. Damn.

But I wonder if this might let me use a PPPoE client, such as my trusty Firebrick, to connect _through_ the device to AA's PPP/L2TP LNS? If so, then I could get IPv6 working. I would still need NAT as I don't have enough additional IPv4 addresses lying around.

That may well be possible.

After thinking about the phrase some more, yes, I would expect it to be true.  :-\
