Справочное Руководство для Netopia r6100

The Netopia R6000 Series ADSL Router suppor ts multiple IP subnets on the Ethernet inter face. You may 
want to configure multiple IP subnets to ser vice more hosts than are possible with your primar y subnet. It 
is not always possible to obtain a larger subnet from your ISP. For example, if you already have a full Class 
C subnet, your only option is multiple Class C subnets, since it is vir tually impossible to justify a Class A or 
Class B assignment. This assumes that you are not using NAT.

If you are using NAT, you can use the reser ved Class A or Class B subnet.

■

Select Default IP Gateway and enter the IP address for a default gateway. This can be the address of any 
major router accessible to the Netopia R6000 Series.

A default gateway should be able to successfully route packets when the Netopia R6000 Series cannot 
recognize the intended recipient’s IP address. A typical example of a default gateway is the ISP’s router.

■

Select Primary Domain Name Server and enter the IP address for a domain name ser ver. The domain 
name ser ver matches the alphabetic addresses favored by people (for example, robin.hood.com) to the IP 
addresses actually used by IP routers (for example, 163.7.8.202). 

■

If a secondar y DNS ser ver is available, select Secondary Domain Name Server and enter its IP address. 
The secondar y DNS ser ver is used by the Netopia R6000 Series when the primar y DNS ser ver is 
inaccessible. Entering a secondar y DNS is useful but not necessar y.

■

Select Domain Name and enter your network’s domain name (for example, netopia.com). Netopia strongly 
recommends that you enter a domain name.

■

Routing Information Protocol (RIP) is needed if there are IP routers on other segments of your Ethernet 
network that the Netopia R6000 Series needs to recognize. If this is the case select Receive RIP and 
select v1, v2, or Both from the pop-up menu. With Receive RIP set to v1, the Netopia R6000 Series’s 
Ethernet por t will accept routing information provided by RIP packets from other routers that use the same 
subnet mask. Set to v2, the Netopia R6000 Series will accept routing information provided by RIP packets 
from other routers that use different subnet masks. Set to Both, the Netopia R6000 Series will accept 
information from either RIP v1 or v2 routers.

■

If you want the Netopia R6000 Series to adver tise its routing table to other routers via RIP, select Transmit 
RIP and select v1, v2 (broadcast), or v2 (multicast) from the pop-up menu. With Transmit RIP v1 selected, 
the Netopia R6000 Series will generate RIP packets only to other RIP v1 routers. With Transmit RIP v2 
(broadcast) selected, the Netopia R6000 Series will generate RIP packets to all other hosts on the 
network. With Transmit RIP v2 (multicast) selected, the Netopia R6000 Series will generate RIP packets 
only to other routers capable of recognizing RIP v2 packets.

To attach a filter set to the Ethernet hub inter face, select LAN (EN Hub) Filter Set and from the pop-up 
menu, select the filter set you want to associate with the LAN inter face. Press Return.

The included filter sets, Basic Firewall or NetBIOS Filter, or any customized filter set you create, can be 
associated with the Ethernet hub, as well as the WAN inter face, as shown below:
