picks up the same request twice

[vicky]

Hello RADIUS-people!

In my radius server I have a certain NAS defined in the clients.conf 
file as (example) :
client 1.1.1.1{
    shortname = one
    secret = oneone
}
and the same NAS in the proxy.conf file like this :
realm one{
    type = radius
    authhost  = 1.1.1.1:1812
    accthost  = 1.1.1.1:1813
    secret = oneone
}

This creates confusion because when receiving a request from this NAS, 
my radius server recognize it twice. One that is proxied and one that is 
"treated" locally (without striping of the realm). How can I solve this 
so that when the request should be proxied it is only proxied and when 
it should be treated locally it is only treated locally?

I hope I made my question clear...

Loads of thanks!
