10.5 LAN Additional Subnet
Use this screen to configure IP alias and public static IP.
IP alias allows you to partition a physical network into different logical networks over the same Ethernet
interface. The Zyxel Device supports multiple logical LAN interfaces through its physical Ethernet
interface with the Zyxel Device itself as the gateway for the LAN network. When you use IP alias, you can
also configure firewall rules to control access to the LAN's logical network (subnet).
If your ISP provides the Public LAN service, the Zyxel Device may use a LAN IP address that can be
accessed from the WAN.
Click Network Setting > Home Networking > Additional Subnet to display the screen shown next.

DESCRIPTION
Select Enable to activate UPnP. Be aware that anyone could use a UPnP application to open
the Web Configurator's login screen without entering the Zyxel Device's IP address (although
you must still enter the password to access the Web Configurator).
Select Enable to activate UPnP with NAT enabled. UPnP NAT traversal automates the process
of allowing an application to operate through NAT. UPnP network devices can automatically
configure network addressing, announce their presence in the network to other UPnP devices
and enable exchange of simple product and service descriptions.
This field displays the index number of the entry.
This field displays the description of the UPnP NAT-T connection.
This field displays the IP address of the other connected UPnP-enabled device.
This field displays the external port number that identifies the service.
This field displays the internal port number that identifies the service.
