Set up /dev/null (no auth) proxy server on NULL realm

[Seiichirou Hiraoka]

Hello folks,

I use freeradius 3.0.4 on CentOS 7.2 (RPM)
And I want to set up /dev/null (without  auth) proxy server on NULL realm.

Now, I set up my proxy.conf as follow.

-----
realm NULL {
        authhost        = 127.0.0.1:1645
        accthost        = 127.0.0.1:1646
        secret          = dummy
}
-----

No service exist in 127.0.0.1:1645, 1646.

When user try to auth without realm (NULL realm),
all authentication going to fail.

I have some question.
1) Is my setting correct ?
2) Is there a way to set the timeout? (I want to set timeout to 0)
3) Any other advice?

Best regards,
