About Port Mapping
To configure OnDemand to redirect traffic for a specific application, you need to know the port numbers the
application uses for the client and server, and then map those ports in AMC. OnDemand listens for incoming
requests on specific ports on the client and then proxies them to the appliance, which forwards the information
to an IP address and port on the application server.
For example, you might configure an IP address and port on the client (such as
127.0.1.1:23) to the host or
IP address and port on the destination server, such as
Some applications—such as email—use multiple ports for different protocols. In this case, you must configure
OnDemand to listen on several different ports. This configuration can also be useful for configuring OnDemand
to work with several different applications. The below image shows OnDemand configured to
work with three applications over five different ports.
Example: OnDemand configuration
In this example OnDemand is configured to listen on port 23 for telnet and port 1494 for Citrix. For email
requests it is listening on port 25 (SMTP), port 110 (POP3), and port 143 (IMAP).
