Some 3rd party applications, such as SSL VPN clients, do not support connecting though a loopback proxy. This document provides information on adding a list of one or more addresses to bypass to the proxy.pac file hosted by the Symantec Endpoint Protection (SEP) client Web Traffic Redirection (WTR) Local Proxy Service (LPS).
On SEP for Mac clients which are using WTR, this bypass functionality can be achieved by updating the local proxy.pac and restarting the LPS component. You need to have admin permission to carryout the changes to your client system.
The local proxy.pac can be found in the following path:
This file can be replaced with a modified proxy.pac created and validated similar to Windows clients - refer to Bypass Endpoint Protection Web Traffic Redirection using LPSFlags.exe.
if (shExpMatch(url, 'http://captive*'))
return "PROXY ";
return 'PROXY localhost:<<port>>';
Refer to the attached sample proxy.pac file.
