Figure 3-4. Select Function dialog box.
Select the function of the WAN Ethernet port by selecting IP Routing (NAT
Enabled)
or IP Routing (NAT Disabled). If you are using NAT Enabled, you
may also select Enable PPPoE.
• Select IP Routing (NAT Enabled) to allow local LAN clients to share one
external IP address for accessing the Internet. This option is most often used
when the Router is connected to a DSL or cable modem, or when the IP
segment of the server needs firewall protection.
• Select IP Routing (NAT Disabled) to allow the Router to function as a router
between the IP segment of the server and another IP segment. This option is
ideal for organizations needing to segment workgroups.
• Select Enable PPPoE to use the Router with a time-base, rather than fixed-cost
DSL modem connection. Enter the User Name and Password provided by
your ISP. This option is most often used when connecting via DSL to the
Internet.
NOTE
Enable PPPoE is valid only when IP Routing (NAT Enabled) is selected.
