Hello ! I have change the version of freeradius, before I had the 1.0.4 version and now the last CVS. I have a problem with the proxy configuration ... so I have change some things for have a "result". Like, before in the users file I rejected the request with an other realm, and at the end of the file I reject ... For example, for netA before I had DEFAULT Realm != "NetB", Realm != "NULL", Auth-type := Reject [...] DEFAULT Auth-Type := Reject And now I must comment this line for A proxy request at B. When A proxy request at B, and B try to response at B ... A "Received Unknown packet code 11from client 147.173.3.249 port 1812: Cannot validate signature Dropping packet without response." You know this error ? Thanks for your help Regards, Configuration For A ## In proxy.conf ## realm netB { type = radius authhost = IPRadiusB:1812 accthost = IPRadiusB:1813 secret = secretAB nostrip } ## In clients.conf ## client IPRadiusB { secret = secretAB shortname = cric nastype = other } /\/\/\ For B /\/\/\ ## In proxy.conf ## realm netA { type = radius authhost = IPRadiusA:1812 accthost = IPRadiusA:1813 secret = secretAB nostrip } ## In clients.conf ## client IPRadiusA { secret = secretAB shortname = cric nastype = other } ## And in the radiusd.conf ## proxy_requests = yes $INCLUDE ${confdir}/proxy.conf
