client's shortname cast the real IP

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
