WAN Ethernet Configuration screen
The WAN Ethernet Configuration screen appears as follows:
•Address Translation Enabled allows you to specify whether or not the router performs Network Address
Translation (NAT) on the Ethernet WAN port. NAT is enabled by default.
•Local WAN IP Address allows you to manually configure an IP address for use on the Ethernet WAN port.
The value 0.0.0.0 indicates that the device will act as a DHCP client on the Ethernet WAN port and attempt
to acquire an address from a DHCP server. By default, the router acts as a DHCP client on the Ethernet
WAN port.
•The Local WAN IP Mask field becomes visible if you specify a Local WAN IP Address. This allows you to
manually configure an IP subnet mask for use on the Ethernet WAN port. This item is visible only if you
have configured a non-zero Ethernet IP Address; otherwise, the router obtains a subnet mask via DHCP.
•The NAT Map List and NAT Server List options are set to the defaults, Easy-PAT List and Easy-Servers.
These provide standard NAT mappings. For more advanced NAT configurations, see “Multiple Network
Address Translation” on page 3-1.
•NAT Options allows you to specify IP Passthrough, allowing a single PC on the LAN to have the router’s
public address assigned to it. See “IP Passthrough” on page 3-27.
•If you set Stateful Inspection Enabled to Yes, you can enable a security feature for computers on your LAN
when NAT is disabled. See “Stateful Inspection” on page 2-23.
•The Filter Set pop-up allows you to associate an IP filter set with the Ethernet WAN port. See “About Filters
and Filter Sets” on page 9-17.
•Remove Filter Set allows you to remove a previously associated filter set.
•Enable PPP over Ethernet is Off by default. If your service provider uses PPPoE authentication toggle this
to On.
