About port lists

Port lists
 are collections of ports, port ranges, or port lists that can be assigned to firewall rules.
Firewall rules use port lists to allow or deny access to specific ports in IP packets. They compare a packet's source port and/or destination port with the ports in a port list. If there is a match, the rule takes an action, such as accepting or dropping the packet. Port lists must contain at least one entry. You cannot create an empty port list; you cannot remove an entry in a port list if it is the only one.
Before nesting a port list inside a port list, check to be sure this option is supported on the BIG-IP® device where you intend to deploy the port list.

Clone port lists

You can clone a port list to create a copy of it, which you can then edit.
  1. Click
    Configuration
    SECURITY
    Network Security
    Port Lists
    .
    The Port Lists screen opens.
  2. Click the check box next to the port list you want to clone.
  3. Click
    Clone
    .
    A copy of that port list is created with the same name, but with
    -CLONE
     appended to the name and a blank
    Description
     field.
  4. Change the port list as needed.
  5. Save your work.
The new port list is defined and you can now assign it to a firewall rule.

Rename port lists

You rename a port list when you want to make that name more accurate or distinct. Renaming a port list causes a new port list to be created and the old port list to be deleted in a single transaction. All references to the old port list are updated to refer to the renamed port list.
  1. Click
    Configuration
    SECURITY
    Network Security
    Port Lists
    .
  2. Select the check box next to the port list to rename.

    Rename
    .
    A dialog box displays.
  4. Enter the new name in the dialog box and click
    Save
    .
    The BIG-IQ system shows the status of the renaming operation in the dialog box.
  5. Click
    Close
     to exit the dialog box.
The port list has been renamed.

Deploy port lists

If you want to do a quicker deployment by only deploying the port list portion of a configuration, you can do a partial deployment of the port list, instead of deploying the entire configuration.
  1. Click
    Configuration
    SECURITY
    Network Security
    Port Lists
    .
    The Port Lists screen opens.
  2. Click the check box next to the port list you want included in the partial deployment.
  3. Click
    Deploy
    .
The system displays the selected port list, with options for partial deployment selected.
Continue the partial deployment process.

Delete port lists

You can delete port lists that you no longer use to avoid confusion in the user interface.
  1. Click
    Configuration
    SECURITY
    Network Security
    Port Lists
    .
    The Port Lists screen opens.
  2. Click the check box next to the port list to delete.
  3. Click
    Delete
    .
  4. In the confirmation dialog box that opens, click
    Delete
     to confirm the removal.
