Configuring browsers to use the appliance Web proxy

In order for user-based access controls to prompt for login and password, each browser on the LAN must be
configured to use the Web proxy of the UTM Firewall appliance. The example given is for Microsoft Internet
Explorer 6. Instructions for other browsers should be similar; refer to their documentation for details on
using a Web proxy.
