# Configuring the Firewall on Gateway/StandAlone Installer (Windows)

You can configure the Gateway/StandAlone installer firewall on the Windows operating system.

A firewall profile is a way of grouping settings, such as firewall rules, connection security rules, and so on, that are applied to the system depending on where the system is connected.

The Windows operating system has three profiles, Public, Private, or Domain. You must enable one of these profiles appropriately based on your connection type.

After the firewall is enabled, inbound settings must have LSA as an exception. By default, inbound settings block all incoming connections unless specified as a rule or as an exception. You must add nginx.exe \port number as an exception.

Perform the following steps to add nginx.exe\port number as an exception:

1. Go to Control Panel > Windows Firewall > Allow a program or feature through Windows Firewall.
2. Select Allow Another Program.
3. Browse to the folder where LSI Storage Authority is installed.
4. From the LSIStorageAuthority installation folder, select nginx.exe.

   Usually nginx.exe is installed under the C:\Program Files (x86)\LSI\LSIStorageAuthority\server location.

   nginx.exe is the web server used by LSA as an interface with remote systems.

5. Click Add or select the check box to allow nginx.exe as an exception.
6. Click OK.

   Alternatively, you can also create a new rule and set the profile type to unblock LSA from the firewall.
