How to assign IPs from different pools (sqlippool) depending on which NAS the request comes from

Hi all, I need to assign IPs from different subnets (pools) depending on which NAS the request comes from. Right now i'm using sqlippool with only one pool (main_pool) populated with one subnet, 172.20.174.0/23. I need to split this subnet in 2 (ie. 172.20.174.0/24 and 172.20.175.0/24) assigning different pool names (ie. pool_A for 172.20.174.0/24 and pool_B for 172.20.175.0/24) in radippool. What i want to do is: - if a user comes from NAS-A then he should be assigned an IP from pool_A - if a user comes from NAS-B then he should be assigned an IP from pool_B How can this be done? Thanks for help. aqx -- "Madness, like small fish, runs in hosts, in vast numbers of instances." Nessuno mi pettina bene come il vento.
