Hello All freeradius mailinglist I would appriciate you help Description a telephony service provider is sending Radius req to my RADIUS server who proxy them to a backend server I have configured a free radius server Version 1.1.0 to act as a proxy server to proxy the request to a backend server These are the configuration file clients.conf and the proxy.conf Client.conf client 172.28.185.31/32 { secret=secretgprs1 shortname=RADIUS_GGSN Proxy.conf realm NULL { type = radius authhost=LOCAL accthost=172.31.201.98:1813 (backend server) secret=secretgprs1 } # # This realm is for ALL OTHER requests. # realm DEFAULT { type = radius authhost=LOCAL accthost=172.31.201.98:1813 secret=secretgprs The problem I have noticed that radius request are not proxied at all So I started to dig in and found that freeradius will not proxy accounting If the attribute User -Name is missing As you can see I made some logs and u can see very vividly the problem. I made my own test to emulate the problem with a radius client and as u can see it was proxies The big Q is how to I force the freeradius to pass the request and not to check these header or maybe to use some sort of INJECTION To the header .
