HowTo: IPv6 over PPPoE on the Ubiquiti EdgeRouter Lite 3-Port EdgeMAX Router

The new 1.2.0beta2 version of the EdgeMAX software on the EdgeRouter Lite has the following entry in its changelog:

[PPPoE] Add IPv6 settings for PPPoE client interfaces, which allows a PPPoE client interface to work with IPv6 address

So how does that work and how can we use it ?
Ubiquiti EdgeRouter Lite 3-Port EdgeMAX Router
Our ISP, Andrews & Arnold, provides native IPv6 over PPPoE, so we thought we would test it.

Portable POE power source

The Smart PowerBank PoE 16V is a really handy device for wireless installers and surveyors, in fact anyone who needs POE power and isn’t near mains power:

Simply a nicely packaged battery pack which supplies 16V DC @ 600mA to your POE device, you can connect it up like this:

HowTo: Managing POE for multiple radios

A typical wireless broadband provider/WISP usually has multiple radios, each with their own POE connection.

Here’s a way of providing Gigabit POE with the ability to power cycle individual radios:

For Gigabit POE we use a MikroTik RouterBoard Gigabit Passive PoE Injector:

Each POE injector plugs into the main router and has  power fed to it  from a single 28V PSU via a relay, i.e. there is one relay per POE injector.

‘WISP in a box’?

Does this sound familiar?

“We have multiple internet lines to our office with some spare capacity and we want to sell internet services to our local area as we know they don’t have good internet from the xDSL mainstream providers. What items do we need to put such a system together? We have limited technical skills in this business, so if you could be very specific in the list of parts required and the trade costs for each item, that would be great! We intend selling internet to our local town which is about 500 houses and we can get 8Mbps service on each of our 4 phone lines. Do you think that would be enough speed for those 500 users, i.e.32Mbps as I’ve been told we can get away with 50:1 contention which is the same that BT uses? I have heard about bonding lines together, but on talking to our ISP they don’t know what we mean, so doubt they can do that themselves. Therefore can you also give us advice on a suitable device that can bond them together please and thus bypass our ISP as they can’t help us? I’ve read on their website that MikroTik can do bonding and can also be used for the core of a wireless ISP business, so that’s why we contacted yourselves. We have now secured access to a roof top that can see the majority of the town, but we also want to feed some farms in the distance about 10km away. Although there are some trees and the odd building in the way, I can just about see the farms between all the obstructions, so the wireless should work fine shouldn’t it? I have read that 802.11n can work around corners, so it will work easily through just a few conifer trees, right? I will forward you some photos we took from the roof if that helps?  Our capital budget is only about £1000 for this project, which I reckon if we use MikroTik will be enough money to make it be successful.  What are your thoughts?  Don’t forget, we need a complete list of everything we need to order and how it all connects together, once we get that we’ll send you a bank transfer immediately!”
