No Response from radius server

[Muhammed Buvaydani]

I have freeradius 3.0 which is installed on ubuntu 18.10 ,
I am working on hotspot system using Mikrotik with freeradius , I was able to send login Request from Mikrotik to radius server without any problem , but then I enabled Ufw in ubuntu machine ,
then I disabled UFW ,
Now Mikrotik can send request to freeradius but freeradius can not send response to Mikrotik , I don't know what is the problem , I disabled UFW and even I removed it from  the server ,but still Mikrotik Can not get response from Radius
this is the debug of Freeradius

as u see from the last line , Freeradius sending Access-accept to Mikrotik , but this response not received by mikroitk and Mikrotik through

Login Feild No Response From Radius

I tested Mikrotik with another freeradius server and it is working without any problem

So , I think there are somethings which prevent  the response packet to Mikrotik .
