The WAN IP Interface page appears.
Enable Interface: You can disable the inter face by unchecking the checkbox. However,
doing so will disable all ability for your LAN users to connect to the WAN using the Gateway.
Address Mapping (NAT): Specifies whether you want the Gateway to use network
address translation (NAT) when communicating with remote routers. NAT lets you conceal
details of your network from remote routers. By default, address mapping is enabled.
Restrictions: This setting determines the types of traffic the Gateway accepts from the
WAN. Admin Disabled means that Gateway traffic is accepted but administrative com-
mands are ignored. None means that all traffic is accepted. When PPP is enabled, Admin
Disabled is the default.
ISP Username: This is the username used to authenticate your Gateway with the Service
Provider's network. This value is given to you by your Service Provider.
ISP Password: This is the password used to authenticate your Gateway with the Service
Provider's network. This value is given to you by your Service Provider.
Connection Type: The pulldown menu allows you to choose to have either an uninter-
rupted connection or an as-needed connection.
