DESCRIPTION
Press [SPACE BAR] to select From ISP, User Defined or None and press
[ENTER]. These fields are not available on all models.
Select From ISP if your ISP dynamically assigns DNS server information. (In
this case, the ISP assigns the WAN IP address too. See Menu 4.) The field to
the right is read-only, and it displays the IP address provided by your ISP.
Select User-Defined if you have the IP address of a DNS server. You might get
it from your ISP or from your network. Enter the IP address in the field below.
Select None if you do not want to use this DNS server. If you select None for
all of the DNS servers, you must use IP addresses to configure the ZyXEL
Device and to access the Internet.
Select DNS Relay if you want to use the ZyXEL Device's IP address. In this
case, the ZyXEL Device finds out the IP address of the DNS server (based on
RFC 1877). Then, it forwards DNS queries from DHCP clients to this server
and sends the response back to the DHCP clients.
If you select User-Defined in the field above, enter the IP address of the DNS
server in this field.
This field is available if you select Relay in the DHCP field. Enter the IP
address of the DHCP server for the network.
Enter the IP address of your ZyXEL Device in dotted decimal notation; for
example, 192.168.1.1 (factory default).
Type the subnet mask assigned to you by your ISP or network administrator. If
they did not provide one, use the default value.
Use this field to control how much routing information the ZyXEL Device sends
and receives on the subnet.
None - The ZyXEL Device does not send or receive routing information on the
subnet.
Both - The ZyXEL Device sends and receives routing information on the
subnet.
In Only - The ZyXEL Device only receives routing information on the subnet.
Out Only - The ZyXEL Device only sends routing information on the subnet.
Select which version of RIP the ZyXEL Device uses when it sends or receives
information on the subnet.
RIP-1 - The ZyXEL Device uses RIPv1 to exchange routing information.
RIP-2B - The ZyXEL Device broadcasts RIPv2 to exchange routing
information.
RIP-2M - The ZyXEL Device multicasts RIPv2 to exchange routing information.
You do not have to enable multicasting to use RIP-2M. (See RIP Version.)
Select which version of IGMP the ZyXEL Device uses to support multicasting
on the LAN. Multicasting sends packets to some computers on the LAN and is
an alternative to unicasting (sending packets to one computer) and
broadcasting (sending packets to every computer).
None - The ZyXEL Device does not support multicasting.
IGMP-v1 - The ZyXEL Device supports IGMP version 1.
IGMP-v2 - The ZyXEL Device supports IGMP version 2.
Multicasting can improve overall network performance. However, it requires
extra processing and generates more network traffic. In addition, other
computers on the LAN have to support the same version of IGMP.
If you want to partition your LAN interface into subnets, press [SPACE BAR] to
select Yes and press [ENTER]. Menu 3.2.1 appears.
