How to Open Ports in the Windows XP Internet Connection Firewall for Office-Logic Notifications

After you turn on Internet Connection Firewall, Office-Logic Notifications for E-mail, Phone Messages, and Chat modules may stop working as they should. How can you work around this?

To work correctly, Office-Logic must receive information over the network. The information enters your computer through an inbound port. Your computer must have the correct inbound port open so that the Internet Connection Firewall (ICF) can allow this information to pass through. Office-Logic Groupware requires that you manually open UDP port 512 so that the programs can work correctly. Below you'll find step-by-step instructions on how to manually open ports in Internet Connection Firewall.

Important Opening ports in ICF can create a security risk and leave your computer vulnerable. Only open ports when you absolutely need to.

To manually open ports in ICF:


Click Start, click Control Panel, click Network and Internet Connections and then click Network Connections.
