mysql ip access control

I would like to do the ip access control by using a irule. However, I failed in the following way.

pool-allowhost-01 have kept some mysql.

when CLIENT_ACCEPTED {
    if { [IP::addr [IP::remote_addr] equals 192.168.1.0/24] } {
         pool pool-allowhost-01
    } else {
         reject
    }
}

allowed host can not access pooling mysql.

[localhost ~]$  mysql -u user -ppass -h lbaddr
