We are not seeing this issue that you are reporting but would like to replicate what you are seeing. If you send us your configuration file, I will load it and try it out locally. Please change any password sensitive information from the configuration. Also if you are not comfortable posting it on support community, you can send us through private message.
One thing I noticed that you are using UDP port 3389 for RDP session and I assuming that LAN device to whom you are trying to establish RDP session is listen at UDP 3389 instead of TCP(by default RDP listens at TCP 3389). Can you please verify this.
Did this person send you the config file? If so were you able to see what was going wrong? I have noticed that noone seems to finish these cases to a resolution point. It would be great if there as some sort of closure to these posts in the fom of a correct answer or a statement that the orignal poster has abandoned it.
We are yet to receive the config file from Scott but if you are facing a similar issue can you forward me configuration file as well as describe the symptom what you are seeing. If you do not want to post the configuration file here, please send it to email@example.com. Please remove password sensitive related information.
By the way, the issue for Allan Lowe in this post above is resolved and you can check the link he has provided in this post.
