How to Open Ports in the Windows Firewall

To work correctly, the FMU server must be able to send and receive informa- tion over the network. The information enters your computer through an inbound port. After you turn on a firewall, the firewall will not allow FMU to use these inbound ports. You must make some adjustments for FMU Server to communicate with the terminals. The host PC must have the correct inbound ports open in the firewall to allow this information to pass through.

Table 4 is a list of ports with instructions on manually opening the ports that the Host PC can communicate correctly with the terminals. Following Table 4 are step-by-step instructions for manually opening ports in Windows Firewall. These instructions are specific to Windows XP with Service Pack 2 (SP2) installed. For other types of firewalls, or Windows Firewall prior to SP2, please refer to the documentation for your product.
