As title, I captured a FTP packet which is encapsulated by a UDP header, how do I decode it ? My version is 3.4.2 thanks!

Are these UFTP packets?

Are these TFTP packets?

No, these are traditional FTP packets. In version 3.4.2, I have no idea to decode them, but in old version(1.x), it’s easy to decode them just click & apply,!

What kind of encapsulation is used to encapsulate the TCP-FTP packets in UDP packets (assuming you mean FTP-over-TCP when you say "traditional FTP packets"). Can you share an exaple capture?
