Question

Hello, may I ask the IPV4 address of this specified radius client. You can use pattern matching syntax, how to match multiple IP addresses, and what is the syntax? For example, I want to add 10.0.0.1, 10.0.0.4，192.168.7.7, how to write these three addresses

Hi A

To match multiple IP addresses using pattern matching syntax, you can use wildcards or specify a range of IP addresses. Here's how you can write the pattern to match the IP addresses you mentioned:

Using wildcards:

• To match any IP address that starts with "10.0.0", you can use the pattern "10.0.0.*".
• To match the specific IP address "192.168.7.7", you can simply use "192.168.7.7".

Using a range:

• To match the IP addresses in the range of 10.0.0.1 to 10.0.0.4, you can use the pattern "10.0.0.[1-4]".

Using these patterns, you can specify multiple IP addresses in a RADIUS client configuration or any other similar context that supports pattern matching.

another method:

To match multiple IP addresses in a RADIUS client, you can use the following pattern matching syntax:

^(10.0.0.1|10.0.0.4|192.168.7.7)$

The ^ and $ characters represent the beginning and end of the string, respectively. The pipe character (|) represents a logical OR, so the pattern matches any of the three IP addresses.

You can also use a CIDR notation to match a range of IP addresses. For example, the following pattern matches all IP addresses in the 10.0.0.0/24 subnet:

^10.0.0.0/24$

The CIDR notation consists of the IP address, a forward slash, and the subnet mask. The subnet mask is a number that represents the number of bits in the IP address that are used for the network portion of the address. In this example, the subnet mask is 24, which means that the first 24 bits of the IP address are used for the network portion of the address and the last 8 bits are used for the host portion of the address.

To add the three IP addresses to the RADIUS client, you would need to create a new RADIUS client and specify the pattern matching syntax or CIDR notation for the IP addresses.

Here are the steps on how to add a RADIUS client with multiple IP addresses:

1. Open the RADIUS server console.
2. Click on the "RADIUS Clients" tab.
3. Click on the "Add" button.
4. In the "Name" field, enter a name for the RADIUS client.
5. In the "IP Address" field, enter the pattern matching syntax or CIDR notation for the IP addresses.
6. Click on the "Save" button.

The RADIUS client will now be added and will be able to authenticate users from any of the IP addresses that match the pattern matching syntax or CIDR notation.
