I have a computer (host) with FileMaker Pro 13 Advanced and set a file for sharing across the network. I am accessing to this file from a client computer w/FMP13 from outside the LAN (internet). I can access and open the file but after a certain time (5-10 min) I get a message telling that the communication with host has been interrupted and all windows are closed.
Should I open ports (5003) in the router located at the client side? Any ideas about what could be happening?
