Want to summarize with AI?

Overview

Required only if your Cloud-Delivered Firewall Management Center cannot communicate with the machine on which TS Agent is installed.

If your Cloud-Delivered Firewall Management Center cannot communicate with the machine on which TS Agent is installed, you must use a proxy with the HTTPS protocol enabled.

The way you do this is up to you; for example, you might have a commercial proxy and use a Windows system proxy with HTTPS enabled to communicate with it.

Note

This task is not required to use an On-Prem Firewall Management Center with the TS Agent or if you are not using Security Cloud Control at all.

Set Up an Application Proxy

This task provides one suggested option to configure a proxy on the Windows Server on which the TS Agent is running. Cisco provides no assurance this procedure will work in your situation. For more information, consult your proxy provider and Windows documentation.

Before you begin

You must have already set up a proxy server; doing so is beyond the scope of this documentation.

Procedure

	1.	Log in as Administrator to your Windows Server.
	2.	As Administrator, open the following file in a text editor: `\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config`
	3.	Paste the following in `machine.config` in the `<system.net>` section. Replace the sample IP address and port with your proxy server's IP address and port. `<! -- Configuration for TS Agent --> <system.net> <defaultProxy> <proxy autoDetect="false" bypassonlocal="false" proxyaddress="http://192.0.2.197:3128" usesystemdefault="false" /> </defaultProxy> </system.net> <! -- Configuration for TS Agent -->`
	4.	Save your changes to `machine.config` and exit the text editor.
	5.	Restart the server for the changes to take effect.
