IP Pool assigned by the ACS

We are implementing the VPN 3015 Concentrator and using ACS to assign IPs to the VPN clients. Want to use subnet as a pool, but I can not find the way to assign the right mask. I guess, the ACS detects that this is a class A network and assigns mask to the clients. Is there any way to hardcode it to

Thank you,

It is recommended to reconfigure the settings in the VPN concentrator and the ip pools on the ACS:

On the VPN Concentrator, choose Configuration > System > Address Management > Assignment > Use Address from Authentication Server > Apply in order to choose the authentication server option for IP address assignment.

On the Cisco VPN 3000 Concentrator, choose Configuration > System > Servers > Accounting Servers.

Add the details for the ACS in order to specify the ACS as an Accounting Server. This allows the ACS to see what IP addresses are in use and assign free IP addresses.

In the ACS, go into either the User Setup or the Group Setup in order to provide the IP address.

Choose VPN Client IP Address Assignment.

Choose Assigned from AAA server pool. An IP address pool on the Authentication Authorization Accounting (AAA) server assigns the IP address.
