Local LAN IP address information to obtain
Your ISP will need to provide you with the following information:
■
The default gateway IP address
■
Remote IP address
■
Local IP address or addresses and subnet mask
Note:
In a single IP address service, your ISP will refer to your computer’s IP address. However, when your
connection is configured with a router, this becomes the router’s WAN IP address.
■
Primary and secondary domain name server (DNS) IP addresses
■
Domain name (usually the same as the ISP’s domain name unless you have registered for your own
individual domain name)
Note:
The default gateway, WAN address and mask, DNS, and domain name are all obtainable via WAN DHCP,
if your ISP supports it.
With Network Address Translation
If you are using NAT, you should obtain the following:
■
If you are connecting to a remote site using Network Address Translation on your router, your provider will
not define the IP address information on your local LAN. You can define this information based on an IP
configuration that may already be in place for the existing network. Alternatively, you can use the default IP
address range used by the router, where 192.168.1.1 is the default IP address of the router.
Without Network Address Translation
If you are
not
using Network Address Translation, you will need to obtain all of the local LAN IP address
information from your ISP and you will need to pay for an IP address for each device on the network.
If you are not using NAT, you should obtain:
■
The Ethernet IP address for your Netopia R910
■
The Ethernet IP subnet mask for your Netopia R910
■
An IP address for each device on your network, in the same network range as the Netopia R910.
