For example, I would like to limit each vpn client only 2GB daily traffic，How to do that？
Thanks.

Assign a VLAN per user and do this in your linux operating system.

Sorry，Can you explain it in detail？
What I imagined just like AAA（by RADIUS）, but I do not know how to operate。

When you add a user in the virtual hub, you can define a VLAN ID.
You may add a tap device(e.g. tap_hub1).
Then, add one VLAN interface(e.g. tap_tap.1) for each user and bridge them using a linux bridge.
You can measure the traffic according to the adapter. If it reaches the limit, you can add an iptables rule to filter the traffic and redirect them to a web server showing a quota exceeded notice. Finally, you can record the value, flush the iptables rules every day at 00:00 and measure the traffic with reference to the last record.
