## Edit an existing Rule through CLI

1. Log in to the Nodegrid device CLI console with an **admin**account.
2. Navigate to the firewall **Chain**which contains the rule.
3. List all available rules with the **show**command:

```plaintext
[admin@nodegrid INPUT]# show
  rules  target  source net4     destination net4  protocol  input interface  output interface  packets  bytes
  =====  ======  ==============  ================  ========  ===============  ================  =======  ======
  0      ACCEPT  127.0.0.1                                                                      3979     251243
  1      ACCEPT  192.168.56.101                                                                 0        0
  2      ACCEPT  192.168.1.1                                                                    0        0
```
4. Navigate into the rule to be change with its rule number.

```plaintext
[admin@nodegrid INPUT]# cd 2/
```
5. Use the **set**command to create the new rule settings. Press **TAB twice**to see all available options.

```plaintext
[admin@nodegrid 2]# set protocol=tcp destination_port=443
```
6. Use the **commit**command to save and activate the changes.

```plaintext
[+admin@nodegrid 2]# commit
```
7. Use the **show**command to see the current values for the rule.

```plaintext
