ProSecure Unified Threat Management (UTM) Appliance Reference Manual

The Known PCs and Devices table contains a list of all known PCs and network devices that are assigned dynamic IP addresses by the UTM, or have been discovered by other means. Collectively, these entries make up the Network Database.

For each attached PC or device, the Known PCs and Devices table displays the following fields:

•Checkbox. Allows you to select the PC or device in the table.

•Name. The name of the PC or device. For computers that do not support the NetBIOS protocol, the name is displayed as “Unknown” (you can edit the entry manually to add a meaningful name). If the PC or device was assigned an IP address by the DHCP server, then the name is appended by an asterisk.

•IP Address. The current IP address of the PC or device. For DHCP clients of the UTM, this IP address does not change. If a PC or device is assigned a static IP address, you need to update this entry manually after the IP address on the PC or device has changed.

•MAC Address. The MAC address of the PC or device’s network interface.

•Group. Each PC or device can be assigned to a single LAN group. By default, a PC or device is assigned to Group 1. You can select a different LAN group from the Group pull-down menu in the Add Known PCs and Devices section or on the Edit Groups and Hosts screen.

•Action. The Edit table button that provides access to the Edit Groups and Hosts screen.

Note: If the UTM is rebooted, the data in the Known PCs and Devices table is lost until the UTM rediscovers the devices.
