Choosing IP Pool based on NAS-Identifier in Cisco Radius Server


We have a configuration with 2 NAS and one Cisco Radius server, with one VPN5008 in the middle. We would like to provide some redundancy/load sharing to such configuration, i.e., one user goes to 1 nas, next to the other, etc. Such configuration was working before when there weren't radius server and the ip address were allocated via a DHCP server, with two differents Pools, one for each nas.

The problem is that it seems that the Radius server doesn't support to choose the ip pools via the NAS-Identifier. If we choose to set only one ip pool, there is no way to know to which nas we need to route the traffic. Any ideas?

thanks in advance.
