The application is configured to retry three times, so I get three packets as above, and no response from FR.
So there's something on the system blocking the packets. iptables, ebtables, nftables, etc. As Alan already said, FreeRADIUS will tell you if it receives packets. It's not saying anything, so it's not receiving anything. tcpdump is showing packets, so they're hitting the server. Not much else to add here. It's an OS issue. -- Matthew
