IP Setup, SmartIP and Network Address Translation 10-17
To go to the IP Address Ser ving screen, select IP Address Serving in the System Configuration screen and
press Return.
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,
Dynamic WAN clients, and MacIP/KIP clients (if you have the AppleTalk kit installed) are automatically
enabled.
■
Select Number of Client IP Addresses and enter the total number of contiguous IP addresses that the
Netopia R2121 will distribute to the client machines on your local area network.
■
In the screen example shown above, five 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, Dynamic WAN, and/or MacIP.
■
Example: Your ISP has given your Netopia R2121 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
Appendix C,
“Understanding IP Addressing.” ). 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.
