Step 1. Create a list. |
In the Groups pane, click Add and give a name to the IP address list. |

Step 2. (Optional) Specify the list update address. |
Specify the address of the server where the updatable list is stored. For more details on updatable lists, see later in this chapter. |
|
Step 3. Add IP addresses. |
In the Selected group addresses pane, click Add and enter the addresses. An IP address entry can be in the form of an individual IP address, IP address/subnet mask, or IP address range (192.168.1.5, 192.168.1.0/24, or 192.168.1.5-192.168.2.100, respectively). |
The administrator can create custom IP-address lists and distribute them centrally to all computers where UserGate is installed. To create such a list, follow these steps:

|
Step 1. Create a file with the desired IP addresses. |
Create a file named list.txt with the IP address list. IP addresses in the text file should be presented in a column without punctuation, for example: x.x.x.x y.y.y.y z.z.z.z |
|
Step 2. Create an archive containing this file. |
Put the file in a ZIP archive named list.zip. |
|
Step 3. Create a version file for the list. |
Create a file named version.txt and specify the list version number inside it, such as 3. On each update of the list, the version number must be incremented. |
|
Step 4. Upload the files to a web server. |
Upload the list.zip and version.txt files to your website so that they can be downloaded. |
|
Step 5. Create an IP address list and specify an update URL for it. |
On each UserGate server, create an IP address list. When creating the list, select Updatable as the list type and enter the address for downloading updates in http://x.x.x.x or ftp://x.x.x.x format. UserGate will check for a new version on your website according to the set update download schedule. The schedule can be configured in the list properties. The available options are:
With the Advanced option, a crontab-like format is used where the date/time string consists of six space-separated fields. The fields specify the time as follows: (minutes: 0-59) (hours: 0-23) (days of the month: 1-31) (month: 1-12) (days of the week: 0-6, where 0 is Sunday). Each of the first five fields can be defined using:
An asterisk or range spacing: used for spacing out values in ranges. The increment is given after a slash. Examples: "2-10/2" means "2,4,6,8,10" while "*/2" in the "hours" field means "every two hours". |
