• 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.
• Obtain WAN address via DHCP allows you to toggle WAN DHCP Off and On. DHCP is On by default. so that
if you do not change the setting, the Router will acquire its WAN IP address automatically. By default, the
router acts as a DHCP client on the Ethernet WAN port and and attempts to acquire an address from a
DHCP server.
• The Local WAN IP Address field allows you to manually configure an IP address for use on the Ethernet
WAN port. This field only becomes visible if you toggle Obtain WAN address via DHCP to Off.
• 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 “Multi-NAT” on
page 4-1.
• 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 4-27.
• 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 3-3.
• 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 10-20.
• Remove Filter Set allows you to remove a previously associated filter set.
• The WAN Ethernet Speed Setting is configurable via a pop-up menu. Options are:
• Auto-Negotiation (the default)
