Obtain IP Address Automatically: Your service provider may tell you that the WAN IP
Address for your Gateway is static. In this case, disable this checkbox and enter the IP
Address and IP Netmask from your Service Provider in the appropriate fields.
IP Address: This is the IP Address from your Service Provider when using static IP
addressing.
IP Netmask: This is the Netmask from your Service Provider when using static IP
addressing.
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.
Advanced:
If you click the Advanced link the Advanced WAN IP Interface configuration page
appears.
RIP Receive Mode: Routing Information Pro-
tocol (RIP) is needed if there are IP routers on
other segments of your Ethernet network that
the Netopia Gateway needs to recognize. Set
to Off, Netopia Firmware Version 7.6.1 will
accept information from either RIP-1 or RIP-2
routers. With Receive RIP Mode set to RIP-1, the Netopia Gateway will accept routing infor-
mation provided by RIP packets from other routers that use the same subnet mask. Set to
RIP-2, Netopia Firmware Version 7.6.1 will accept routing information provided by RIP
packets from other routers that use different subnet masks.
From the pull-down menu, choose Off, RIP-1, RIP-2, RIP-1 compatibility, or RIP-2 with
MD5.
Enable Proxy ARP: Checking the checkbox will enable the Gateway to respond when it
receives an Address Resolution Protocol message for devices behind it.
