Client network (WiFi) blocks access to remote host

I have found many discussions and pointers about opening ports and/or port forwarding on the network/machine that FileMaker Server is running but I haven't found a answer to a problem which must be quite common:

 

We are running FileMaker Server 12 on server that is set up correctly with the necesssary ports open. We can access this server with FileMaker Pro and FileMaker Go from pretty much anywhere through G3/LTE networks and also from many locations over WiFi. But it seems that some WiFi networks are blocking access to our FileMaker Server even though they are open for http, https, ftp, etc. We have encountered this on a network of a larger company but also on a schools network. This obviously is a big problem when developing FileMaker Go applications that are supposed to be able to easily connect to the data on the server.

 

Are there any specific instructions that we can give to the IT departments of this schools and companies? Do they have to open access to port 5003 on their WiFi network as well? Is that all they have to do or do they also have to allow some other protocoll besides http? As said before, this is not related to the way the host machine is set up. The block is on the client network.

 

Thank you for any help you can provide.

Thomas
