Trouble "SQL Based IP Pool"

[Leander S.]

This is my actual output for a user who has attribute: "Pool-Name = mypool"

root ~ #  radtest leander 123456 10.1.10.80:1812 2 schaefer
Sending Access-Request of id 79 to 10.1.10.80 port 1812
        User-Name = "leander"
        User-Password = "123456"
        NAS-IP-Address = 255.255.255.255
        NAS-Port = 2
rad_recv: Access-Accept packet from host 10.1.10.80:1812, id=79, length=122
        Framed-Protocol = PPP
        Framed-MTU = 1492
        Framed-Compression = Van-Jacobson-TCP-IP
        Session-Timeout = 86400
        Framed-IP-Address = 255.255.255.254
        Service-Type = Framed-User
        Framed-IP-Netmask = 255.255.255.255
root ~ #

^^ Btw. Why is my NAS-IP-Address = 255.255.255.255 ? I didn't write that 
in clients.conf? Where might I change that?

... just once again .. because I can't get rid of the guess that my 
mistake is in the data I typed into the DB table:

INSERT INTO radippool (pool_name, framedipaddress, nasipaddress, 
expiry_time, pool_key) VALUES ('mypool', '192.168.5.1', '10.1.10.80', 
'2008-12-31 00:00:00', '0');
^^ 1. What is pool_key standing for? Why do _I_ have to write that in 
manually?
^^ 2. What is expiry_time good for if there is already an  
lease-duration = 3600 configured in the postgresqlippool.conf? And why 
do I get forced to use unix timestamp instead of using a simple time in 
secounds when it'll be expired?


Thank you
