• IP Address: Enter your (static) public IP address. Auto displays if you selected Auto as the IP Address
Assignment in the previous screen.
The following fields display if you selected static IP address assignment.
• IP Subnet Mask: Enter the subnet mask for this WAN connection's IP address.
• Gateway IP Address: Enter the IP address of the router through which this WAN connection will send
traffic (the default gateway).
• First / Second DNS Server: These fields display if you selected static IP address assignment. The Domain
Name System (DNS) maps a domain name to an IP address and vice versa. Enter a DNS server's IP
address(es). The DNS server is extremely important because without it, you must know the IP address
of a computer before you can access it. The Zyxel Device uses these (in the order you specify here) to
resolve domain names for VPN, DDNS and the time server. Leave the field as 0.0.0.0 if you do not want
to configure DNS servers.
2.1.2.1 Possible Errors
• Check that your cable connection is coming from the correct interface you're using for the WAN
connection on the Zyxel Device.
• Check that the interface is connected to the device you're using for Internet access such as a
broadband router and that the router is turned on. The LED of the interface you're using for the WAN
connection on the Zyxel Device should be orange.
• If your Zyxel Device was not able to obtain an IP address, check that your Internet access information
uses DHCP as the WAN connection type. If it fails again, check with your Internet service provider or
administrator for correct WAN settings.
• If your Zyxel Device was not able to use the IP address entered, check that you were given an IP
address, subnet mask and gateway address as part of your Internet access information. Re-enter your
IP address, subnet mask and gateway IP address exactly as given. If it fails again, check with your
Internet service provider or administrator for correct IP address, subnet mask and gateway address
and other WAN settings.
