FreeBSD 10.1 has been End-of-Life since December 2016 and is not supported any more. You should update your system as soon as possible.

Second remark, don't open RDP (3389) to the world if you value your security. Your initial post actually had your external IP address and I had no problems connecting to it. You have now masked it in the post (which is good) but it still means it's open to the world.

UDP is a connection-less protocol.
