(RADIATOR) Unknown reply received in AuthRADIUS - with Attachments

Hello Miko -

The problem you have is due to the fact that you are sending the proxy 
request to one IP address and the reply is coming back from a different 
IP address:

Mon Jul 29 10:22:51 2002: DEBUG: Packet dump:
*** Sending to port 1645 ....


Mon Jul 29 10:22:51 2002: DEBUG: Packet dump:
*** Received from port 1645 ....

Radiator keeps track of proxied radius requests using the IP address and 
port number to which the request was sent, expecting the reply to come 
back from the same place.

I suspect you either have multiple NIC cards in this machine, or you are 
using a cluster of some sort.

If you can't fix the target host, you can use the 
ServerHasBrokenAddresses parameter in the AuthBy RADIUS clause.

Have a look at section 6.29.20 in the Radiator 3.1 reference manual.
