CHAPTER 49
Device Insight
This chapter describes how to:
• View the status and information of the clients connected to the Zyxel Device.
• Create profiles to block specified clients.
49.1 Device Insight Overview
Device Insight displays the status of the clients connected to the Zyxel Device, such as if a client is
sending traffic to the Zyxel Device or if a client’s MAC address is in the CDR block list.
It also displays the basic information of the clients. The clients shown may include clients connected to
the Zyxel Device:
• A - Using wired connections.
• B - Through access points (APs) using wired connections.
• C - Through access points (APs) using WiFi connections.
• D- Through built-in access points using WiFi connections.
• E- Using SecuExtender (IPSec VPN clients).
Use Device Insight to identify and monitor clients connected to the internal LAN/VLAN DMZ networks of
the Zyxel Device in the same IP subnet. This feature collects client information, including:
• Hostname
• IP address and MAC address
• Operating system
• Category, such as mobile phones or computers
• Connected interface
You can create a profile based on clients' categories and operating systems, and then apply the
created profile to the Zyxel Device security policies. For example, company A on the Zyxel Device LAN1
wants to block its subsidiary employees on LAN2 from accessing the company A local networks with
their mobile phones. Company A can create a profile that includes all operating systems mobile
phones, and then apply it to the LAN2_To_LAN1 policy. Clients using mobile phones on the Zyxel Device
LAN2 will be blocked from accessing the Zyxel Device LAN1.
Note: To collect clients’ information using Device Insight, the clients must be in the same IP
subnet in the LAN/VLAN/DMZ networks behind the Zyxel Device. Information from
clients that are in different IP subnets in the LAN/VLAN/DMZ networks might not be
collected correctly as traffic must pass through another router or a layer-3 switch to the
Zyxel Device.
