Deciding on an ISP account
 
Your ISP may offer various Internet access account plans. Typically, these plans var y by usage charges and the 
number of host IP addresses supplied. Evaluate your networking needs and discuss them with your ISP before 
deciding on a plan for your network. 
 
Setting up a Netopia R7200 account
 
Check whether your ISP has the Netopia R7200 on its list of suppor ted products that have been tested with a 
par ticular configuration. If the ISP does not have the Netopia R7200 on such a list, describe the Netopia R7200 
in as much detail as needed, so your ISP account can be optimized. As appropriate, refer your ISP to Netopia’s 
Web site www.netopia.com for more information.
 
Obtaining an IP address
 
Typically, each network computer that requires Internet access requires its own unique IP address. If some or 
all network computers require simultaneous Internet access, obtain a block of IP host addresses large enough 
for each computer to have its own address, plus one for the Netopia R7200. 
Consider expected growth in your network when deciding on the number of addresses to obtain. Alternatively, 
you can use the Network Address Translation feature of Smar tIP.
 
SmartIP
 
The Netopia R7200 SDSL Router suppor ts the Smar tIP™ feature, which includes Network Address Translation. 
Network Address Translation provides Internet access to the network connected to the Netopia R7200 using 
only a single IP address. These routers translate between the internal or local area network (LAN) addresses 
and a single external IP address, and route accordingly.
