A typical CM Server configuration allows Internet Web clients to access CM Server through a firewall. Communication between CM Server and Web-based hosts use the Hypertext Transfer Protocol Secure (HTTPS) protocol and are secured by SSL. Communication between CM Server and hosts on a private intranet use ordinary remote procedure calls (RPCs) and are not secure. Ordinary RPCs cannot communicate through a firewall, so you cannot place a firewall between a CM Server and the host servers.
