Features and enhancements

There were no features or enhancements in this release.


The following issues have been fixed in this release:

ID Number Description
807269-1 Previously, the DNS Relay Proxy service did not recover to its former functional state in case of errors and/or service restart. The system generated several DNS queries, and the DNS split scope did not work. This issue has been fixed, and now when the service is restarted, the VPN tunnel reconnects, and the DNS exception rules re-populate.
937637-8 Fixed the issue where Edge Client did not follow best practices when used to establish a VPN through a browser.
942421-1 Previously, in some cases, the DNS Relay Proxy service worker thread encounters errors and terminates by leaving the service in a waiting state. This issue has been fixed.
949933-9 Fixed the issue on Windows, where the Client Troubleshooting Utility (CTU) tool bundled with APM clients did not follow the best practices.
958429-1 The DNS resolution of an excluded hostname may resolve to multiple IP addresses. Previously, if the Edge Client used a different IP address than the one resolved by stonewall service at startup, the service blocked all the traffic, and Edge Client could not connect. This issue has been fixed, and now the Stonewall service updates the DNS exclusions' IP addresses dynamically by periodically resolving hostname exclusions.
961977-1 Fixed the issue that caused macOS clients to be unable to establish a VPN connection ( After upgrading to epsec-1.0.0-936.0.iso on the APM, Edge Client for macOS failed to pass the Access Policy and could not connect to the VPN.
963797-1 Fixed the issue where users could access external sites for a short interval of 30-40 seconds after logging into Windows in locked mode.
967345-1 Previously, Edge Client's Always Connected mode for macOS could temporarily fail to restrict internet access on system startup. The issue is fixed, and now the Always Connected mode restricts internet access when the VPN is disconnected.
973241-1 Fixed the issue where Edge Client for Windows failed to start after rebooting. This happened because the Edge Client got stuck waiting for the Stonewall service and communicating about the disconnected VPN option.
973417-1 Previously, on Windows, the Stonewall service did not recognize the local network on startup. This happened because the Network Location Awareness (NLA) is not activated on the first run, and the Firewall blocked the internet traffic. This issue is fixed, and now NLA detects the local network successfully.
