Monitoring System Performance

.

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 > LAN Setup 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.
