If you are physically connected to the network, then you will display the IP Address as well as the local area network address (192.168.xxx.xxx).
Port 5003 is used to access FileMaker Pro dataase files over the network using FileMaker Pro. If you are using port 591 for Instant Web Publishing, then when using Instant Web Publishing, make sure your browser is pointing to:
