Apex Central allows you to use a proxy server for component/license updates, cloud services, and syslog forwarding.
You can also use the same proxy server for syslog forwarding if you select a SOCKS protocol for the server. Syslog forwarding does not support HTTP protocol proxy servers.
For more information, see Configuring Syslog Forwarding.
