Port Ranges in Server Configuration

The Port Range functionality allows configuring a Server object in Fudo Enterprise with a specified port range. This eliminates the need to create separate servers for each port in scenarios requiring traffic forwarding from multiple ports simultaneously, significantly simplifying the configuration process and reducing manual work.

Configuring a Port Range

  1. From the left menu, select Management > Servers and click + Add Server.

  2. Enter a unique name for the created object (e.g., Server_1).

  3. Go to the Settings section.

  4. In the Protocol field, select the protocol for the server.

  5. In the Destination section, define the parameters of the target server:

    • Select Host, IPv4, or IPv6.

    • Enter the Address of the server and optionally the Mask.

  6. Click Port Range and enter values in the First Port and Last Port fields (e.g., First Port: 22, Last Port: 30).

  7. Click Save and Close.

Note

  • The maximum allowed value for both fields is 65535. If a higher value is entered, it will be automatically set to the maximum value.

  • The number in the Last Port field must be greater than the number in the First Port field. Entering a value in Last Port that is less than or equal to First Port will result in only the First Port value being saved, configuring the server to use a single port instead of a range.

  • When the Port Range option is selected, the automatic upload of certificates or public keys is disabled, requiring manual input.

Server Configuration Prioritization in Case of Conflict

If a server with a port range is configured alongside another server with the same address but a single port within the range of the first server, e.g.:

Server_1 - 10.0.130.100:22-24
Server_2 - 10.0.130.100:23

then Fudo Enterprise will always prioritize the more specific configuration when establishing a connection through port 23, in this case, Server_2.

Note

As a result, if a user with access to Server_1 selects port 23 from the available range but does not have assigned access permissions to Server_2 in Fudo Enterprise, they will not be able to establish such a connection.
