You could use the same ip pool across two NAS servers if you were only using one radius server to assign IPs. I recommend you either make one radius server handle only one NAS, so the ip pools don't collide, or used rlm_sqlipool across them both as Peter pointed out.

Any of the following:
* Don't use the same pool range on 2 servers (What made you think that this
would work?)
* Use a share storage backend (sqlippool with shared database)
