RADIUS is ignoring request to authentication address

Solution 1:

To fix the problem I had to comment out client localhost { and ipaddr = 127.0.0.1 in /etc/freeradius/clients.conf.

Comment out the following

#client localhost {

        #  Allowed values are:
        #       dotted quad (1.2.3.4)
        #       hostname    (radius.example.com)
#       ipaddr = 127.0.0.1

        #  OR, you can use an IPv6 address, but not both
        #  at the same time.
#       ipv6addr = ::   # any.  ::1 == localhost

and then add

client openwrt {
        ipaddr = 192.168.2.1
        secret = testing123
        require_message_authenticator = yes

Allow port 1812 and 1813

sudo ufw allow 1812

sudo ufw allow 1813

Now my router uses radius.
