192.168.1.201 is a Trend controller device responding to a request from the server side, the server side is connected to the mobile WAN and the Trend Device to the local LAN of the router but I will look into your comment with our IT side who is in charge of the server side to make sure its not refusing the FTP traffic. Am I right in assuming the 10.0.1.144 port 18585 is an internal address between LAN and WAN? still brushing up on my knowledge with a lot of the network and routing side
Thank you
