What remote ports should be added in the router for vCloudPoint device remote connection over WAN?

For remote connection with vCloudPoint zero clients over WAN, setting DMZ host is the easiest way but unsafe, therefore, you can add these ports in your router instead.

The broadcast port is fixed using UDP 13389, and the receive port begins with TCP 13389 and extends to at least 3 extra plus 3 for each user. For example, if there are 10 users need to connect remotely, you need to at least add ports of UDP 13389-13389, TCP 13389-13422 (13422 is the minimum and reserve more if possible).
