Netopia R2121, User Reference Manual

Page: 71 / 280

Easy Setup 7-5
1. Select Ethernet IP Address and enter the first IP address from the IP address range your ISP has given
you. This will be the Netopia Router’s IP address.
If Network Address Translation is enabled in the Easy Setup connection profile, the Ethernet IP Address
defaults to an address within a range reser ved by the Internet address administration authority for use
within private networks, 192.168.1.1.
Because this is a private network address, it should never be directly connected to the Internet. Using NAT
for all your connection profiles will ensure this restriction. See
“IP Setup, Smar tIP and Network Address
Translation” on page 10-1 of this guide for more information.
2. Select Ethernet Subnet Mask and enter the subnet mask your ISP has given you. The Ethernet Subnet
Mask defaults to a standard class C mask (for unlimited user models; smaller, for restricted user models).
3. Select Domain Name and enter the domain name your ISP has given you.
4. Select Primary Domain Name Server and enter the IP address your ISP has given you.
5. The Default IP Gateway defaults to the remote IP address you entered in the Easy Setup connection
profile. If the Netopia Router does not recognize the destination of any IP traffic, it for wards that traffic to
this gateway.
Do not confuse the remote IP address and the default gateway’s IP address with the block of local IP
addresses you receive from your ISP. You use the local IP addresses for the Netopia R2121’s Ethernet por t
and for IP clients on your local network. The remote IP address and the default gateway’s IP address
should point to your ISP’s router.
6. To use DHCP and (if installed) MacIP address ser ving, toggle IP Address Serving to On .
Note: For information about dynamic IP address ser ving, see “IP Setup, Smar tIP and Network Address
Translation” on page 10-1 .
