Network Requirements for Off-Server Session Managers

Off-server Session Manager connects to the Notifier subsystem running on the CIC server on port 5597 by default. Every off-server Session Manager machine must be able to access port 5597 of the CIC server (or servers, in a switchover pair).

Session Manager listens on port 3952 for incoming requests.Interaction Desktop and other IceLib-based applications connect to Session Manager on this port.Every server that is running Session Manager, including the CIC server (servers), must have permissions to open port 3952.Every computer that is running an IceLib-based client application must be able to access port 3952 of all Session Managers to which it is allowed to connect.

Some file transfers between IceLib and the server use the HTTPS protocol on port 8019.Every server that is running Session Manager, including one or more CIC servers, must have permissions to open port 8019.Every computer that is running an IceLib-based client application must be able to access port 8019 of all Session Managers to which they are allowed to connect, as well as port 8019 of any CIC servers.

For IceLib-based applications connecting over the Internet, either port 8952 or port 8951 need to be opened on a server running Session Manager (including the CIC server or servers) for WebSocket connections between the application and Session Manager.Ports 8952 or 8951 must not be publicly available over the Internet.Instead, a publicly available reverse proxy must be in place which would direct traffic to the appropriate Session Manager server.See Section 7.11 Connecting IceLib Applications over the Internet for details.
