IP Setup, SmartIP and Network Address Translation 10-9
Press the Escape key when you are finished configuring Expor ted Ser vices to go back to the IP Setup
screen.
Follow these steps to configure IP Setup for your Corporate Netopia R2121:
■
Select Ethernet IP Address and enter the IP address for the Netopia R2121’s Ethernet por t.
■
Select Ethernet Subnet Mask and enter the subnet mask for the Ethernet IP Address that you entered in
the last step.
■
Select Default IP Gateway and enter the IP address for a default gateway. This can be the address of any
major router accessible to the Netopia R2121 such as 127.0.0.2.
A default gateway should be able to successfully route packets when the Netopia R2121 cannot recognize
the intended recipient’s IP address. A typical example of a default gateway is the a corporate dial-in or
ISP’s router.
■
Select DNS Server and enter the IP address for a domain name ser ver. The domain name ser ver matches
the alphabetic addresses favored by people (for example, www.netopia.com) to the IP addresses actually
used by IP routers (for example, 163.7.8.202).
■
If a secondar y DNS ser ver is available, select Secondary DNS Server and enter its IP address. The
secondar y DNS ser ver is used by the Netopia R2121 when the primar y DNS ser ver is inaccessible.
Entering a secondar y DNS is useful but it is not necessar y.
■
Select Domain Name and enter your network’s domain name (for example, netopia.com).
■
Routing Information Protocol (RIP) is needed if there are IP routers on other segments of your Ethernet
network that the Netopia R2121 needs to recognize. If this is the case select
Receive RIP and select v1 ,
v2 , or Both from the popup menu. With Receive RIP set to “v1,” the Netopia R2121’s Ethernet por t will
accept routing information provided by RIP packets from other routers that use the same subnet mask. Set
to “v2,” the Netopia R2121 will accept routing information provided by RIP packets from other routers that
use different subnet masks. Set to “Both,” the Netopia R2121 will accept information from either RIP v1 or
