default gateway per user basis

[Igor Smitran]

Hello. I am new to this list and also to freeradius server.

Can someone please help me?
I have a pppoe server on freebsd. I want to setup freeradius to give 
different ip address block and gateway to users.
I need two pools, and i have a two gateways. One gateway is more expensive 
than the otherone. So, users that pay less will use chiper gateway and vice 
versa. Is this possible?

10x in advance.
