# Adding, Editing, or Deleting an RPC Port Range

An RPC port range restricts iProcess Engine processes to accept incoming RPC requests from within that port range. For more information, see Administering Firewall Port Ranges in TIBCO iProcess Engine Administrator’s Guide.

## Adding an RPC Port Range

To add an RPC port range from the Administration Console, perform the following steps:

| 1. | On the RPC Port Range panel, Click Add RPC Port Range. An Add RPC Port Range dialog box is displayed.

| 2. | On the Add RPC Port Range dialog box, you must define the fields listed in the table here:

RPC Port Range Fields

Field | Description
Range Mode | Defines how servers that use this port range configuration should allocate ports. Specify one of the following values: `0` - Do not use port or RPC ranges. A process can use any port number and RPC number (as assigned by the operating system). `1` - Use port ranges. A process must use a port number allocated from within the defined range but can use any RPC number. `2` - Use RPC ranges. A process must use an RPC number allocated from within the defined range but can use any port number. `3` - Use port ranges and RPC ranges. A process must use both a port number and an RPC number allocated from within the defined ranges. If this value is omitted the range mode defaults to 3.
Port Range Start | The port number that the range should start from. (The range, therefore, ends at Port_range_start + Range_size.)
RPC Range Start | The RPC number that the range should start from. (The range, therefore, ends at RPC_range_start + Range_size.)
Range Size | (Optional) The number of slots in the defined port and/or RPC number ranges. The range size cannot exceed 65535. If this field is omitted, the range size defaults to 20.
Machine ID | The server ID of the machine that you want to add to a port range.

| 3. | On populating all fields, click ADD to add the specified RPC port range.
