#### IP-Groups feature as part of Override Rules feature.

The Override Rules feature allows you to modify original or parent policy settings.

Rules are defined using specific conditions, which can include an IP group based on the declarative policy JSON schema.

When triggered, the rule is applied to the _clientIp_ attribute using the _matches_ function.

'clientIp.matches(ipAddressLists["standalone"])'

Here is a policy example:

```json
{
"policy": {
"name": "ip_group_override_rule",
"template": {
"name": "POLICY_TEMPLATE_NGINX_BASE"
},
"applicationLanguage": "utf-8",
"caseInsensitive": false,
"enforcementMode": "blocking",
"ip-address-lists": [
{
"name": "standalone",
"description": "This is my list of IP addresses",
"ipAddresses": [
{
"ipAddress": "6.5.3.3/32"
},
{
"ipAddress": "6.5.4.2"
}
]
}
],
"override-rules": [
{
"name": "myFirstRule",
"condition": "clientIp.matches(ipAddressLists['standalone'])",
"actionType": "violation",
"violation": {
"block": true,
"alarm": true,
"attackType": {
"name": "Forceful Browsing"
},
"description": "Attempt to access from clientIp",
"rating": 4
}
}
],
"general": {
"trustXff": true
}
}
}
```

The previous example policy contains an IP group with the name "standalone", used for the override rule condition "clientIp.matches(ipAddressLists['standalone'])".
The condition means that the rule enforcement is applied when clientIp is matched to one of ipAddresses in ipAddressList with name "standalone".
The value used for the override condition must exist and exactly match the name in "ip-address-lists".

#### Possible errors

| Error text | Input | Explanation |
| -----------| ------------- | ------------ |
| _Invalid field invalidList_ | _clientIp.matches(invalidList['standalone']);_ | An incorrect keyword was used instead of _ipAddressLists_ |
| _Invalid value empty string_ | _clientIp.matches(ipAddressLists['']_ | An empty name was provided |
| _Failed to compile policy - 'ipGroupOverridePolicy'_ | _uri.matches(ipAddressLists['standalone']);_ | Used _ipAddressLists_ without the _clientIP_ attribute |

IP groups is a feature to organize lists of allowed and forbidden IP addresses across several lists with common attributes.

This allows you to control unique policy settings for incoming requests based on specific IP addresses.

Each IP Group contains a unique name, enforcement type (_always_, _never_ and _policy-default_), and list of IP addresses.


An example of a declarative policy using IP Groups configuration:

```json
{
"policy": {
"name": "IpGroups_policy",
"template": {
"name": "POLICY_TEMPLATE_NGINX_BASE"
},
"applicationLanguage": "utf-8",
"caseInsensitive": false,
"enforcementMode": "blocking",
"ip-address-lists": [
{
"name": "Standalone",
"description": "Optional Description",
"blockRequests": "policy-default",
"setGeolocation": "IN",
"ipAddresses": [
{
"ipAddress": "1.2.3.4/32"
},
{
"ipAddress": "1111:fc00:0:112::2"
}
]
}
]
}
}

```
The example with IP-Group definition in external file external_ip_groups.json:

```json
{
"policy": {
"name": "IpGroups_policy2",
"template": {
"name": "POLICY_TEMPLATE_NGINX_BASE"
},
"applicationLanguage": "utf-8",
"caseInsensitive": false,
"enforcementMode": "blocking",
"ip-address-lists": [
{
"name": "external_ip_groups",
"description": "Optional Description",
"blockRequests": "always",
"setGeolocation": "IL",
"ipAddresses": [
{
"ipAddress": "31.8.194.27"
}
],
"$ref": "file:///tmp/policy/external_ip_groups.json"
}
]
}
}
```
Example of the file external_ip_groups.json

```json
{
"name": "External Ip Groups List",
"description": "Optional Description",
"blockRequests": "always",
"setGeolocation": "IR",
"ipAddresses": [
{
"ipAddress": "66.51.41.21"
},
{
"ipAddress": "66.52.42.22"
}
]
}
```
