Hi again, Thanks for the help, the proxy is working fine now. Now I've another issue: I've to modify the reply items JUST for a Nas, not for the realm. I mean: NAS1 NAS2 | | \---proxy--/ | +---- Customer Radius | +---- My Radius The Proxy is working for realms A e B: My Radius is realm A, meanwhile customer one is for realm B. The problem is that I've to modify on the proxy the reply items JUST for realm B when called by NAS1. I've read the attr-rewrite, but I don't understand how to force to be called only in such this case. Any help? Thanks Andrea No virus found in this outgoing message. Checked by AVG Free Edition.
