Red Hat Bugzilla – Bug 839390
Request: please include --with-udpfromto as compilation parameter
Last modified: 2012-08-07 15:47:21 EDT
Description of problem:
In current version of freeradius there is problem when you have multihomed server with multiple IP addresses. When RADIUS request comes to secondary IP address, UDP reply from RADIUS servers comes back with different - primary - IP address instead of original IP address from requested.
Classic example: imagine using failover scenario with two/more radius boxes which are using VRRP and one virtual IP (VIP) address. When you want to use VIP as IP address of RADIUS server you have a trouble here - responses will come from different (original) IP address instead of VIP as source IP.
My request is to appending single compilation option "--with-udpfromto" which tells freeradius to always use as source address the destination IP address of RADIUS UDP packet request. Nothing more nothing less.
I have just compiled freeradius with this compilation switch by myself and everything is working as expected. Please consider this feature :)
