There is a firewall, somewhere.

If you used the wrong port you'd get port unreachable.

If there's a firewall then you'll get admin prohibited (or possibly 
something else depending on how the firewall is set up).

You didn't say where you are running wireshark. If it's on the RADIUS 
server, then the RADIUS server has the firewall (because you see the 
requests and the responses). If you are capturing elsewhere then 
something from the switch up to the RADIUS server has a firewall.
