Cannot ping any
computer on the LAN.
Cannot get a WAN IP
address from the ISP.
ZyWALL 2WE
Select this check box to allow UPnP-enabled applications to automatically
configure the ZyWALL so that they can communicate through the ZyWALL, for
example by using NAT traversal, UPnP applications automatically reserve a NAT
forwarding port in order to communicate with another UPnP enabled device; this
eliminates the need to manually configure port forwarding for the UPnP enabled
application.
Select this check box to create a static LAN to LAN/ZyWALL rule that allows
forwarding of ports 1900 and 80. Selecting this check box also creates a
dynamic firewall rule every time a NAT forwarding port is reserved for UPnP.
This setting remains active until you disable UPnP or clear this check box.
Clear this check box to have the firewall block all UPnP application packets
(for example, MSN packets) instead of creating a firewall rule for them.
This identifies the ZyXEL device in UPnP applications.
Make sure that you have the correct power adaptor connected to the ZyWALL and
plugged in to an appropriate power source. Check all cable connections.
If the LEDs still do not turn on, you may have a hardware problem. In this case, you
should contact your local vendor.
Check the cable connection between the ZyWALL and your computer or hub. Refer
to the Rear Panel section for details.
Ping the ZyWALL from a LAN computer. Make sure your computer Ethernet card is
installed and functioning properly.
If the 10/100M LAN LEDs are off, check the cable connections between the ZyWALL
and your LAN computers.
Verify that the IP address and subnet mask of the ZyWALL and the LAN computers
are in the same IP address range.
The WAN IP is provided after the ISP verifies the MAC address, host name or user
ID.
Find out the verification method used by your ISP and configure the corresponding
fields.
If the ISP checks the WAN MAC address, you should clone the MAC address from a
LAN computer. Click WAN and then the MAC tab, select Spoof this Computer's
MAC address - IP Address and enter the IP address of the computer on the LAN
whose MAC address you are cloning.
