Summary
A firewall can prevent a Laserfiche Web product from communicating with a Laserfiche Server. See below for instructions on configuring Web Access 8, WebLink 8, and/or Agenda Manager 8 to work with firewalls.
Ports
By default, Laserfiche 8 Server listens on TCP port 80 or 5050. Laserfiche defaults to port 80 except when installed on the 32-bit edition of Windows XP, where Laserfiche defaults to port 5050. The Laserfiche 8 Server broadcasts notifications on port 5051. If there is a firewall between your Laserfiche 8 Server and your web server, ensure ports 80 or 5050, and port 5051 are open on the firewall. You can use the Server Settings node of the Laserfiche 8 Administration Console to modify the default port settings. The Laserfiche 8.0.1 Server (and higher) installation automatically creates a Windows Firewall exception for the Laserfiche Server.
For Laserfiche Rio installations, ensure the listening and notification ports are also open in the firewall (5048 and 5055 by default, respectively).
Web Access 8
See Types of Firewall Configurations, which explains the different types of firewall configurations that can be implemented for Laserfiche Web Access 8.
WebLink 8
See Types of Firewall Configurations, which explains the different types of firewall configurations that can be implemented for Laserfiche WebLink 8.
Agenda Manager 8
In most cases, Agenda Manager 8 is hosted inside of a firewall and is not intended to be public-facing. As a result, detailed instructions on firewall configuration is not necessary. If there is a firewall between your Laserfiche 8 Server and your Agenda Manager 8 Server, ensure the Laserfiche Server's listening and notification ports are open.
Working with a DMZ
If your web product is installed within a DMZ, and you are using Windows Authentication, there are two possible solutions:
