Monitoring Attached Devices
The LAN Groups screen contains a table of all IP devices that the VPN firewall has discovered on
the local network.
To view the LAN Groups screen:
1. Select Network Configuration > LAN Settings from the main menu, and then select the LAN
Groups tab. The LAN Groups screen will display.
2. The Known PCs and Devices database is an automatically-maintained list of LAN-attached
devices. PCs and other LAN devices become known by the following methods:
•DHCP Client Requests. By default, the DHCP server in the VPN firewall is enabled, and
will accept and respond to DHCP client requests from PCs and other network devices.
These requests also generate an entry in the database. Because of this, leaving the DHCP
Server feature enabled (in the LAN Setup menu) is strongly recommended.
•Scanning the Network. The local network is scanned using standard methods such as
ARP. The scan will detect active devices that are not DHCP clients. However, sometimes
the name of the PC or device cannot be accurately determined and will be shown as
unknown.
•Manually Adding Devices. You can enter information in the Add Known PCs and
Devices section and click Add to manually add a device to the database.
