Hi all

I was wondering if anyone using Mikrotik, ever managed to "whitelist" destination addresses while using PPPoE and RADIUS.
I know that Radius just counts up all traffic used, but I've seen some big ISP's that are able to whitelist certain destinations without having traffic to that destination count towards your monthly usage.

I'm guessing they probably have a billing system that has netflow worked in somewhere. So netflow monitors flows to/from the whitelisted destinations, then traffic to that gets subtracted from radius's usage records...
Have anyone managed to set up something like this?

some ISPs use BSD or Linux-based solutions, managing 'whitelisted' addresses in different RADIUS realms, so billing system can skip some realms from accounting

If I understand you right, you mean create two realms, one thats counted and one not counting. Then give the users two usernames for the two different realms?

AFAIR, it's a feature of mpd on FreeBSD - RouterOS doesn't support this

Ah ok. This looks like what you are referring to: http://mpd.sourceforge.net/doc5/mpd37.html#37
I also did a bit of reading and realised that netflow isn't that accurate when used for accounting as it skips ethernet overhead.

Well I doubt I'll use MPD as we also do a hotspot and MT is so nice to use

PPPoE also do not count ethernet overhead, AFAICS - so no difference
