You probably meant he is sending *accounting* requests to you? Please be specific in your wording. > 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 If authhost and accthost are different, there is a bug somewhere. So if you don't receive auth requests anyway and just want to proxy everything that comes in, you'd better set authhost and accthost to the same value. > 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 . How about logging all accounting packets to a detail file and using radrelay? BTW: this injection you are talking about works as well and you don't need radrelay then, and it *could* be done in the hints file, but you would require a patch I submitted some time ago because otherwise hints will ignore those acct packets without User-Name.
