LABEL DESCRIPTION
Enable UPnP Select this check box to activate UPnP on the Zyxel Device. 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).
Enable NAT-PMP NAT Port Mapping Protocol (NAT-PMP) automates port forwarding to allow a computer in a
private network (behind the Zyxel Device) to automatically configure the Zyxel Device to
allow computers outside the private network to contact it.
Select this check box to activate NAT-PMP on the Zyxel Device. Be aware that anyone could
use a NAT-PMP 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).
Allow UPnP or
NAT-PMP to pass
through Firewall
Select this check box to allow traffic from UPnP-enabled or NAT-PMP-enabled applications
to bypass the security policy.
Clear this check box to have the security policy block all UPnP or NAT-PMP application
packets (for example, MSN packets).
Outgoing WAN
Interface
Select through which WAN interface(s) you want to send out traffic from UPnP-enabled or
NAT-PMP-enabled applications. If the WAN interface you select loses its connection, the
Zyxel Device attempts to use the other WAN interface. If the other WAN interface also does
not work, the Zyxel Device drops outgoing packets from UPnP-enabled or NAT-PMP-enabled
applications.
Support LAN List The Available list displays the name(s) of the internal interface(s) on which the Zyxel Device
supports UPnP and/or NAT-PMP.
To enable UPnP and/or NAT-PMP on an interface, you can double-click a single entry to
move it or use the [Shift] or [Ctrl] key to select multiple entries and click the right arrow button
to add to the Member list. To remove an interface, select the name(s) in the Member list and
click the left arrow button.
Apply Click Apply to save your changes back to the Zyxel Device.
Reset Click Reset to return the screen to its last-saved settings.
