change NAS-IP-Address before relaying

sorry all, the first mail had no subject --------------------------------------------------------------------

Hi all,

i want to use FreeRADIUS (1.0.5) as an RADIUS Proxy, and must change the NAS-IP-Address and the User-Realm before sending it to an other Rasius Server. I tried it within the preproxy_users file with

DEFAULT User-Name := `%{Stripped-User-Name:-%{User-Name}}@mycompany.com`, NAS-IP-Address := x.x.x.x

The change of the User-Realm works, but not the NAS-IP-Address. The server sends the authentication requests with its hostname (in detail with the aoutput of the /etc/hostname command).

Any ideas of helpfull information are welcome. Regards Oliver Stutzke
