Usually this occurs if the EAPTLS_MaxFragmentSize is set too large in regards
to the smallest MTU of the path the Radius packets take.
1000 is a low value for an Ethernet infrastructure with a MTU of 1500 but you
might have tunnels or some other media with a smaller MTU in your path.
Another possibility is that the client doesn't trust the radius server
certificate which will cause it to stop further processing too.

The problem is in the log of the radiator, I am only seeing Access-Request and
one Access-Challenge packet, some how challenge stops.
Could you please tell me what am I missing or how can I fixed it?
