I had similar problem for my wireless clients, I came up with an excellent PPPoE solution. It is called www.Mikrotik.com
Its a shame that the pppoe implementation in FreeBSD cant do bandwidth limiting, but the mikrotik(linux yack) implementation does! I am almost sure it can do bandwidth limiting on pptp interfaces too.
You can download a trial version of mikrotik, although you cant use the trial version with wireless, you can try with ethernet, these pppoe and pptp connections.
I am sure you will be little alien to the interfaces of mikrotik for a while but it is similar to cisco ios and they have a quite nice graphical administration tool.
I wonder if your tunnels fail because of some MTU constraints.
If you use pppoe, you can give bandwidth from radius! upload/download different bandwidths are possible. The sky is the limit.

Hi guys.
I have a setup for wireless clients where I use pptp vpn tunnels for my users to be able to auth and connect. The vpn daemon (poptop) talks to freeradius server which against gets user info from MySQL database.
I use dialup_admin to be able to easly add new users.
Everything works great except for one thing.
The users (companies) are unable to create their own VPN tunnels (i.e IPsec) to other places.
It's impossible to tunnel IPsec inside of pptp vpn tunnels.
So maybe running plain PPPoE could solve that problem.
Then I could use WPA for traffic encryption.
Does that sound logical?
I also need some kind of system that will make it possible to give different bandwith to different users.
I though I could set up DUMMYNET with bw restrictions for different subnets with a subnet mask like /16 or similar.
Then give static IP's to my users depending on what bw they are allowed to use. But this approach does not seem to be very flexible.
Is there a way to make radius do bandwith restrictions or run commands against an external application?
I am not "locked" to use BSD, if this works better on Linux then I will use it too.
Thanks YazzY
