I am trying to share FileMaker files on a host that is plugged into a hub. Another computer that is on the network via AIrport (gray base station plugged into hub) is able to share files both ways etc., but has had a hard time consistently seeing the hosted FM files.
-the airport signal strength is high
-both FM apps on each machine is set to TCP/IP
-both machines are on the same subnet

I suspect the port mapping options in the Airport settings could solve this, but I can't figure out what port FileMaker uses...

Any help?
