Help: On setting up freeradius proxy server on v 3.17

16 Jan 2019

      Hi,

I am trying to set up the proxy server for load-balance, Here It was trying
Creating 1 radius as proxy server with below proxy
configuration(proxy.config).

##
proxy server {
    default_fallback = no
}

home_server localhost {
    type = auth

    ipaddr = 127.0.0.1
    port = 1812
    secret = testing123
    response_window = 20
    zombie_period = 40
    revive_interval = 120
    #  Allowed values: none, status-server, request
    status_check = status-server
    check_interval = 30
    check_timeout = 4
    num_answers_to_alive = 3
    max_outstanding = 65536

    coa {
        irt = 2
        mrt = 16
        mrc = 5
        mrd = 30
    }

    #
    limit {
          max_connections = 16
          max_requests = 0
          lifetime = 0
          idle_timeout = 0
    }

}

home_server server01 {
    type = auth
    ipaddr = 10.x.y.z
    port = 1812
    secret = testing123
}

home_server_pool my_auth_failover {
    type = fail-over
    home_server = server01
}

realm example.com {

    auth_pool = my_auth_failover
}

realm LOCAL {
    #  If we do not specify a server pool, the realm is LOCAL, and
    #  requests are not proxied to it.
}

#
#  This realm is for requests which don't have an explicit realm
#  prefix or suffix.  User names like "bob" will match this one.
#
realm NULL {
    auth_pool = my_auth_failover
}

realm DEFAULT {
    auth_pool = my_auth_failover
}

realm "~(.*\.)*example\.net$" {
      auth_pool = my_auth_failover
}

Later I am setting up one   *  home_server = server01*
Here I am using default *proxy*.*config* file.
I started server and send auth request

*the request is going to server01 with below error *

*Ignoring request to auth address * port 1812 bound to server default from
unknown client 10.X.Y.Z port 21473 proto udp*

I thought we may need to add the client entry and added the proxy server as
client in home_server = server01 my creating entry in client.config

*client my,.hostname {        ipaddr          = 10.x.x.x
secret          = testing123        shortname       = twick}*

still getting same error.
What may be I am missing ?
