Requirements for the proxy server
- Port 3128 open for inbound and outbound connections.
- Short path 8.3 file system required. For further information, please refer to this Microsoft article.
Configuring a computer as a proxy server
- Click the Network settings tab. Select an existing Proxy and language settings profile or create a new one.
- Expand the Proxy section and select Adaptive Defense 360 proxy.
- Click Select computer…
- In the computer selection window, click Add proxy server. A list will be displayed with all managed computers that haven’t been designated as proxy server yet.
- Select the computers that will act as a proxy server for all other workstations and servers protected by Adaptive Defense 360.
NOTE: For Linux, it is not possible to add more than one machine as proxy, therefore, there is no fallback mechanism in place.
Revoking the proxy role
- Click the Network settings tab. Select an existing Proxy and language settings profile or create a new one.
- Expand the Proxy section and select Adaptive Defense 360 proxy.
- Click Select computer..
- Click the icon of the computer that you want to stop acting as a proxy.
Fallback mechanism
When a Panda agent cannot connect to the Aether platform, in Windows, the following fallback logic is applied to restore the connection via other means:
- If the Internet connection is configured via corporate proxy or Panda Adaptive Defense 360 proxy and there is no response, an attempt is made to connect directly.
- Internet Explorer: The Panda agent tries to recover the Internet Explorer proxy settings with the profile of the user logged in to the computer.
- If the configuration of the proxy credentials is defined explicitly, this method can?t be used.
- If the Internet Explorer proxy settings use PAC (Proxy Auto-Config) the URL is obtained from the settings file, provided that the protocol is HTTP or HTTPS.
- WinHTTP / WinInet: The default proxy settings are read.
- WPAD (Web Proxy Auto-discovery Protocol): A request is sent to the network via DNS or DHCP to get the URL that points to the PAC settings file.
