Hi again :-(,
I'm quite certain that there's an access request for each channel. I
don't think the access request is identical, and it's really
difficult for me to get a trace, but I'll try and we'll see...
Bear in mind that in a multilink connection it's possible to fire up
just one channel and an hour later fire up the second, so there must
be a second access request. But I'm quite sure that it shouldn't be
very difficult to cope with it as there are other RADIUS products
that do :-)
Cheers,
- --
