Hi Alan,

Please help..Here I have problem that I can't figure out what went wrong!

#radtest MarsNet Mars123 localhost 0 testing123
User-Name = "MarsNet"
        User-Password = "Mars123"
        NAS-IP-Address = 192.168.1.5
        NAS-Port = 0
        Reply-Message = "Hello, MarsNet"

if I change the configuration in radiusd.conf to bind to particular IP address (eth0) then about radtest failed to Accept.
My server configured with DNS / DHCP / iptable firewall (Internet) (eth1) and eth0 connect to Wifi -> D-Link client.
