Re: WISP Authentication - PPPoE Maybe?
It isn't extremely easy for someone to grab some free Internet as we are using WaveRider 900MHz equipment (about to move to Motorola Canopy 900MHz)... while it still isn't impossible by any means, at least someone can't go to walmart and buy equipment capable of associating with our network  .
I'm leaning more towards the route of placing PPPoE concentrators at the tower level and having a centrally located RADIUS server.
Does anyone use Mikrotik as a PPPoE Concentrator? I was wondering if I buy one of their router boards about how many sessions it could support. |

Im using mikrotik on every AP, i use WRAP bords and they do just fine with pppoe access concentrator, plust doing AP on one mpci port and backhaul on the other mpci port, routing and some basic firewall rules.
I see 24-45% of cpu load on the peak hours, where the maximum of 30 pppoe session can be active simultaniously, we dont cross the 30 clients asociated to the same AP. |

Cayuga, ON | I went with a SFF PC 667mhz that will run pfSense, I cant comment on microtik I have not used it, and it looks that pfSense will do everything I need and more. |

So the Mikrotik AP's can only handle 30 simultaneous PPPOE connections? I thought it was 200, I suppose it's licensed for that many?
Or are you referring to 30 clients per AP max in general? Just curious as we run PPPOE bridged through Deliberant AP's down to a Mikrotik router/server as our PPPOE concentrator. We have up to 25 on one AP as our max on an AP.
I would still like to know how many others have put on a single RB532 with SR2 card running PPPOE with 512 and 384 packages? |

I think he is referring to 30 clients per AP, the PPPoE concentrator can handle as much as you have horsepower. The general rule of thumb is, you need 2 mhz of CPU power for each client doing PPPoE, (at least for x86 type architecture) 30 clients = 60mhz needed just for PPPoE, I have no idea how fast a mikrotik board is. |

How many clients...
Using a Mikrotik and a prism card (802.11b) I have, to my own shock, been able to do 70 clients in a pinch. The bandwidth is stretched thin, but it degrades gracefully. I just do dhcp, no pppoe.
Using Mikrotik and SR2s or emp-8602s (senao) it always falls apart badly in the 10 - 20 client range, and it is not a traffic problem. I did not try it using nstream, as it was an existing tower with non-nstreme capable clients.
If anyone has experience doing >40 clients on mikrotik atheros cards, 802.11g or 11a, I'd love to hear your success story. |

Yess, i was referring to 30 clients per AP. We don't cross that number of costumers per AP so we can keep the good performance. As far as pppoe is concerned there is software licence limitation on 200 pppoe tunels if you have Level4 licence, i think that is more than a RB or WRAP can handle, but based on the percentage I gave you for 30 clients you can guess how many more clients the WRAP board CPU can handle. (it has 233mhz x86 procesor and 128 ram). |

| I built a router/server with a P4 3.0 ghz with 1gb ram. This handles routing, PPPOE, NAT, firewall, etc. We currently have 44 active PPPOE sessions on this server and the total memory is 884.5, and free is 850.3. That's averaging less than 1mb / user including all of the other resources being used. |
