freeradius server works only on localhost

[Ron Eggler]

Hi All,

I'm new here. <https://unix.stackexchange.com/posts/655577/timeline>

I have a freeradius server setup but it only works on my localhost. I do 
see the frames from the remote host coming in on Wireshark, so the 
requests do arrive but on the client I just get:

|radtest MAC foo host:1812 0 bar Sent Access-Request Id 67 from 
0.0.0.0:47922 to host:1812 length 82 User-Name = "MAC" User-Password = 
"foo" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 Message-Authenticator = 
0x00 Cleartext-Password = "foo" Sent Access-Request Id 67 from 
0.0.0.0:47922 to host:1812 length 82 User-Name = "MAC" User-Password = 
"foo" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 Message-Authenticator = 
0x00 Cleartext-Password = "foo" Sent Access-Request Id 67 from 
0.0.0.0:47922 to host:1812 length 82 User-Name = "MAC" User-Password = 
"foo" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 Message-Authenticator = 
0x00 Cleartext-Password = "foo" (0) No reply from server for ID 67 socket 3 |

While on localhost I get:

|radtest MAC foo 127.0.0.1:1812 0 bar Sent Access-Request Id 12 from 
0.0.0.0:50005 to 127.0.0.1:1812 length 82 User-Name = "MAC" 
User-Password = "foo" NAS-IP-Address = 127.0.1.1 NAS-Port = 0 
Message-Authenticator = 0x00 Cleartext-Password = "foo" Received 
Access-Accept Id 12 from 127.0.0.1:1812 to 127.0.0.1:50005 length 20 |

How do I open server access up to the outside, as well?

Thanks!
