Issue/Introduction

You have a proxy in the environment that permits cross-communication between IPv4 and IPv6. With this proxy enabled, you notice that access through a remote console to Symantec Endpoint Protection Manager (SEPM) 14.2 does not launch when you expect it to.

Remote consoles include Java Remote Console, Web Console, and Reporting console access.

Resolution

When you enable cross-communication between IPv4 and IPv6 with any proxy, the following support matrix applies:

Networking of Symantec
Endpoint Protection Manager
Networking of
client computer*
Result
IPv4 and IPv6 IPv4 Access through all remote consoles
IPv4 and IPv6 IPv6 Access through Reporting console
No access through Java Remote Console and Web Console
IPv4 only IPv4 Access through all remote consoles
IPv4 only IPv6 Access through Web Console and Reporting Console
No access through Java Remote Console
IPv6 only IPv4 Access through Reporting Console
No access through Java Remote console and Web Console
IPv6 only IPv6 Access through all remote consoles

* The client computer used to access the remote console.

Note: The server on which the Symantec Endpoint Protection Manager is installed must have the IPv4 stack installed, even if it is disabled. See the system requirements for Symantec Endpoint Protection Manager, under “Other environmental requirements.”

To enable cross-communication for the proxy

  1. Open a command window:
    • On a 64-bit computer: Double-click C:\Windows\SysWOW64\cmd.exe.
    • On a 32-bit computer: Click Start > Run > cmd.exe.
       
  2. Enter one of the following commands, substituting the IP address of the proxy server, and the proxy’s port number:
    • netsh winhttp set proxy IPv4_address_of_proxy_server:proxy_port
    • netsh winhttp set proxy [IPv6_address_of_proxy_server]:proxy_port

      Note: For a computer configured for IPv6 networking, use the IPv6 address of the proxy server.
      For a computer configured for IPv4 networking, use the IPv4 address of the proxy server.
       
  3. Open Internet Explorer, and click Tools > Internet options > Connections > LAN settings.
     
  4. Check Use a proxy server for your LAN, and enter the appropriate IP address and port number for the proxy.
     
  5. Next to the port number, click Advanced, and then enable Use the same proxy server for all protocols.
     
  6. Click OK until Internet Options closes.
