Is the server multihomed ?
It often happends that the server will recieve a request on one IP address and send out a reply using a different address with a multihomed system.
If your system has multiple IP addresses, u can set "bind_address" to the one you want to use.

Subject: Server logs say users authenticate, but they don't (Now with more details!)
This isn't a duplicate, I've just included more information about our
configuration.
We have a Cisco AS5300 for our dialup pool. It is able to log into our new
FreeRadius server and make authentication requests, but users are not able
to authenticate.
It's very strange, because FreeRadius produces logs like this:
Thu Nov 2 11:06:24 2006 : Auth: Login OK: [XXXXXX/XXXXXX] (from client
dialup port 8)
But the client gets "Error 691: Your username or password are incorrect".
I can tell that it's authenticating properly, because when a user gets
their password wrong, I see this instead:
Thu Nov 2 11:02:20 2006 : Auth: Login incorrect: [user1/somepass] (from
client dialup port 13)
Thu Nov 2 11:02:20 2006 : Auth: Login incorrect: [user1/somepass] (from
client dialup port 13)
We're using FreeRadius' mysql support for authentication, and I'm
absolutely positive that part is working fine. It even creates accounting
data in the database.
This is what we have in the users file:
DEFAULT Framed-Protocol == PPP, Simultaneous-Use == 1
Framed-Protocol = PPP,
Framed-Compression = Van-Jacobson-TCP-IP
