The Global WAN Mode controls must be adjusted as required by your ISP.
The settings you enter here determine how the Wireless Gateway will be
identified to your ISP's equipment and other machines on the global Internet.
• If your ISP has given you a fixed IP address to use on the WAN link,
click the Specify Global IP Address control. Then click in (or tab to)
the three boxes below it and type in the global IP address, subnet mask,
and default gateway that the ISP has instructed you to use.
• If your ISP will assign the Wireless Gateway an IP address and related
settings using DHCP (the Dynamic Host Configuration Protocol),
simply click Obtain Global IP Address Automatically (DHCP).
DHCP is commonly used on cable links.
• If your ISP uses PPPoE (the Point-to-Point Protocol over Ethernet),
click the PPP over Ethernet (PPPoE) control. The ISP will have
given you a “username” or user ID and a password to use on the
PPPoE link; click in (or tab to) the corresponding boxes under this
control and type in the strings your ISP has instructed you to use. In
some cases — especially if the Wireless Gateway's WAN port is
networked directly to more than one broadband modem or router —
you will need to type an identifying string into the Service Name box.
Your PPPoE link might allow you to save on connection charges by
disconnecting when the link is not in use and reconnecting when
someone on the LAN wants to access the Internet. If this is the case,
you have the option of setting the Connect on Demand control to Yes
or
No
. If you click
No
, you will have to use the
PPPoE Connect
and
PPPoE Disconnect commands in the Tools menu to take the Wireless
Gateway on line and off line. (You can, alternatively, use the Manager
Server software to set a connection schedule; see the Manager Server
manual for details.) If you click
Yes
, be sure to set the
Maximum Idle
Time control also. The Wireless Gateway will then automatically
disconnect whenever the specified amount of time passes without
anyone on the LAN accessing the Internet.
DNS IP Addresses
In almost all cases your ISP will provide you with the IP addresses of two or
more DNS (Domain Name System) servers. Click in the boxes provided and
type in the addresses carefully. If you set the Wireless Gateway up as a DHCP
