autenticating with realm null only in one NAS

[rgreiner]

I need to configurate freeradius to allow NULL realms only from one or 
two NAS, and all the other must have a realm in the login. What would be 
the best way to do this?

(using freeradius 2.0.2, in a Debian etch platform.)

I tried to add the following in the Users file:

DEFAULT NAS-IP-Address=="1.2.3.4", Proxy-To-Realm := "realm1.com"
DEFAULT NAS-IP-Address=="1.2.3.5", Proxy-To-Realm := "realm1.com"

DEFAULT Realm == NULL, Auth-Type := Reject
        Fall-Through = 1

In proxy.conf, I added the following entry at end of the file:

realm realm1.com {
        pool = my_auth_failover
        # nostrip
}

(I left the example entries from the file enabled.)

freeradius -X display:
In this entry, I did not use a realm in the login, still it connected. 
Any ideas how would be the best way to configure this?
