FreeBSD veneza.mar.com.br 6.2-STABLE FreeBSD 6.2-STABLE #0: Tue Jun 19 14:06:36 BRT 2007     root@veneza.mar.com.br:/usr/src/sys/i386/compile/SMP  i386
>Description:
I had a FreeBSD server, 4.11, wich served PPPoE connections to wireles clients.
It worked perfectly until I migrated to 6.0 - STABLE.

In 6.0 - STABLE, if the FreeBSD server reboots or some client lost its
connection, the respective tun still actives and the ip address still
actives too. The connection isn't killed by PPPoE Server and the client
can't connect again.

In 4.11 the same problem doesn't exists.

It's a bug of pppd or some configuration changes since 4.11?

I'm using radius to restrict double login.

Thanks.

>How-To-Repeat:
make a PPPoe connection with any client, reboots with reset button the
client or the server. The client can't connect again if simultaneous-use = 1
and the server is 6.x

And try it again, with FreeBSD 4.x in the server side.

>Fix:
I believe that if it's a bug in the 6.x version, why not use the same
4.x version of pppd?

I've compiled the 4.xx version of PPP and PPPd on 6.20-STABLE, but the
problem persists.
