Radius test only success in the local machine, but can't success remote machine - freeradius

Question

I install the freeradius in centos7 through ./configure&&make&&make install.
after make the server running. the local test is valid:
[root#iZ2zebgsn1haj8gu0447fiZ raddb]# radtest steve testing localhost 0 testing123
Sending Access-Request of id 151 to 127.0.0.1 port 1812
User-Name = "steve"
User-Password = "testing"
NAS-IP-Address = 172.17.120.248
NAS-Port = 0
Message-Authenticator = 0x00000000000000000000000000000000
rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=151, length=71
Service-Type = Framed-User
Framed-Protocol = PPP
Framed-IP-Address = 172.16.3.33
Framed-IP-Netmask = 255.255.255.0
Framed-Routing = Broadcast-Listen
Filter-Id = "std.ppp"
Framed-MTU = 1500
Framed-Compression = Van-Jacobson-TCP-IP
But in the remote machine, it seems that there's no response from the radius server machine:
[root#iZ2zebgsn1haj8gu0447fiZ raddb]# radtest steve testing 211.71.149.221 0 testing123

radclient: no response from server for ID 149 socket 3
Here's my configure file:
clients.conf：
client 211.71.149.221{
ipaddr=211.71.149.221
secret = testing123
short = test-client
nastype = other
}
users
steve Cleartext-Password := "testing"
Service-Type = Framed-User,
Framed-Protocol = PPP,
Framed-IP-Address = 172.16.3.33,
Framed-IP-Netmask = 255.255.255.0,
Framed-Routing = Broadcast-Listen,
Framed-Filter-Id = "std.ppp",
Framed-MTU = 1500,
Framed-Compression = Van-Jacobsen-TCP-I
I didn't use database,so I didn't make a change to the radiusd.conf.

Answer 1

Your failing radtest is sending the request to a remote server with IP 211.71.149.221. Your clients.conf defines a client with client IP-adress 211.71.149.221. I'm guessing that that is NOT the IP from which your request is coming from.
