client's shortname cast the real IP

[Min Qiu]

Hi,

I have:

client 10.1.2.0/24 {
  secret  = secretkey
  shortname = 10.1.2.x
}

The problem is the log has only 10.1.2.x, not the real NAS IP.  
However, taking the shortname out will generate error when the
radiusd runs.  What I can do to have the server log the real 
NAS ip.  Of cause, I don't want to do

client 10.1.2.1 ...
client 10.1.2.2 ...
...
client 10.1.2.254 ...

I have FC4 and freeradius 1.0.4 installed

Thanks,

Min
