Follow these steps to configure IP Address Ser ving:

■

If you enabled IP Address Ser ving either by using Smar tStar t or in Easy Setup, DHCP, BootP clients, and 
Dynamic WAN clients are automatically enabled.

■

Select Number of Client IP Addresses and enter the total number of contiguous IP addresses that the 
Netopia R310 will distribute to the client machines on your local area network.

■

In the screen example shown above, a hundred Client IP addresses have been allocated.

■

Select 1st Client Address and enter the first client IP address that you will allocate to your first client 
machine. For instance, on your local area network you may first want to figure out what machines are going 
to be allocated specific static IP addresses so that you can determine the pool of IP addresses that you will 
be ser ving addresses from via DHCP, BOOTP, and/or Dynamic WAN.

Note: On a  Netopia R310 the factor y default IP Address ser ving settings are:

1st Client Address: 192.168.1.3 

Number of Client IP Addresses: 100

(this allows for one static address at 192.168.1.2 for the ser ver) 

■

Example: Your ISP has given your Netopia R310 the IP address 192.168.6.137, with a subnet mask of 
255.255.255.248. The subnet mask allocated will give you six IP addresses to use when connecting to the 
ISP over the Internet (for more information on understanding IP addressing refer to 

). Your address range will be from .137-.143. In this example you would 

enter 192.168.6.138 as the 1st client address, as the router itself must have an IP address.

■

To enable DHCP, select Serve DHCP Clients and toggle it to Yes. DHCP ser ving is automatic when IP 
Address Ser ving is enabled.

Note: When the remote router requests a DNS ser ver address via IPCP, the Netopia R310 will supply 
whatever DNS address that is either manually configured or acquired dynamically.  This feature allows a 
DNS to be ser ved that was acquired via DHCP.

■

The Netopia R310 defaults to a DHCP lease time of one hour.  If this is unnecessarily brief for your network 
environment, you can configure the DHCP Lease Time (Hours) field.  You can enter any number up to and 
including 168 (one week) for the DHCP lease.

If your network uses NetBIOS, you can enable the Netopia R310 to use DHCP to distribute NetBIOS information.

NetBIOS stands for Network Basic Input/Output System. It is a layer of software originally developed by IBM 
and Sytek to link a network operating system with specific hardware. NetBIOS has been adopted as an industr y 
standard. It offers LAN applications, a variety of “hooks” to carr y out inter-application communications and data 
transfer. Essentially, NetBIOS is a way for application programs to talk to the network. To run an application that 
works with NetBIOS, a non-IBM network operating system or network inter face card must offer a NetBIOS 
emulator. Many vendors either provide a version of NetBIOS to inter face with their hardware or emulate its 
transpor t layer communications ser vices in their network products. A NetBIOS emulator is a program provided 
by NetWare clients that allow workstations to run applications that suppor t IBM’s NetBIOS calls.

Select Serve NetBIOS Options and press Return. The DHCP NetBIOS Options screen appears.
