Port 69 is just one of thousands of ports inside your "firewall".It is used sometimes by viruses and certain programs to get information or to sneak in and mess up or break your computer.You can unblock it via your firewall menu.

UDP Port 69 refers to Trivial File Transfer Protocol (TFTP), a file transfer protocol (FTP), implemented on User Datagram Protocol (UDP), that uses a very small amount of memory, so it was used to boot hardware devices that had no real data storage devices (fixed disk/hard drives). TFTP only reads and writes files (or mail) from/to a remote server. It cannot list directories, and currently has no provisions for user authentication, so unblocking the protocol might open a vulnerability to attacking your workstations. However, if you're sure you want to do this, you simply create a new rule, or modify existing rules, on your firewall(s), choosing whether you want to block the protocol inbound, outbound or both.
