Bug with multiple IPs?

I have freeradius running on a machine with 2 IPs. I have it binding to all available IPs. xxx.xxx.xxx.44 is the main IP of the machine xxx.xxx.xxx.26 is the secondary IP. (eth0:1) When a request comes in on .26 freeradius processes it and THEN sends the reply out .44! Is this the way it is suppose to be acting?
