bandwidth and volume limit

[fadli]

A) bandwidth limit
You can use WISPr-Bandwidth-Max-Down and WISPr-Bandwidth-Max-Up attribute to
limit the bandwidth. they should be inserted in radreply or groupradreply
table. But you need to modify NAS firewall to force the attribute to user.

I use chillispot. In the NAS I force all user Internet session to use tun0
device which is created by chillispot. This is my rule for forward chain :

# iptables -P FORWARD DROP
# iptables -F FORWARD
# iptables -A FORWARD -o tun0-j ACCEPT
# iptables -A FORWARD -i tun0 -j ACCEPT

b) volume limit.
I face the same problem too when dealing with freeradius 1.1.3. but after
upgrade to freeradius 1.1.4, the problems solved itself, no more
Session Time generated, but only AcctInputOctet. I suggest you to upgrade to
Freeradius 1.1.4. but if you insist to stick on current version, you must
create some perl script to help freeradius server to generate AcctInputOctet
for accounting.
