Hi.
i have a problem proxy.
Proxying to auth-server, and "NAS-IP-Address" was automatically added by proxy.
can I stop it?
I used ntradping-1.5 and freeradius-2.1.10.
--hosts--
ntradping-1.5 10.233.55.200
proxy (freeradius-2.1.10) 10.233.36.101
auth-server (freeradius-2.1.10) 10.233.36.100
--debug log--
