This article describes how to configure Symantec Endpoint Protection 12.1 (SEP) to use a proxy for communication with the Symantec Endpoint Protection Manager on Windows Vista and above. This article uses netsh commands for Windows Hypertext Transfer Protocol (WinHTTP). More information on these commands can be found in the Microsoft TechNet Library.

Note: The steps in this article will configure proxy settings on the computer for WinHTTP. This will affect all applications on the computer which use WinHTTP, including SEP.

Run the following command, depending on the operating system of the computer. Replace servername and port as appropriate to your environment. After running the command, either stop and start SEP services or restart the computer in order to use the new settings.

For 32-bit editions of Windows Vista, Windows Server 2008, Windows 7, and Windows 2008 R2 computers:
    netsh winhttp set proxy proxy-server="servername:port"

For 64-bit editions of Windows Vista, Windows Server 2008, Windows 7, and Windows 2008 R2 computers:
    C:\Windows\SysWOW64\netsh winhttp set proxy proxy-server="servername:port"

For both 32- and 64-bit editions of Windows 8, Windows 2012, and above:
    netsh winhttp set proxy proxy-server="servername:port"

Example command for Windows 8:
    netsh winhttp set proxy proxy-server="proxysvr:8080"
