LABEL DESCRIPTION
DNS Servers
First, Second and
Third DNS Server
Select Obtained from ISP if your ISP dynamically assigns DNS server
information (and the ZyXEL Device's WAN IP address). Use the drop-down
list box to select a DNS server IP address that the ISP assigns in the field to
the right.
Select UserDefined if you have the IP address of a DNS server. Enter the
DNS server's IP address in the field to the right. If you chose UserDefined,
but leave the IP address set to 0.0.0.0, UserDefined changes to None after
you click Apply. If you set a second choice to UserDefined, and enter the
same IP address, the second UserDefined changes to None after you click
Apply.
Select None if you do not want to configure DNS servers. You must have
another DHCP sever on your LAN, or else the computers must have their
DNS server addresses manually configured. If you do not configure a DNS
server, you must know the IP address of a computer in order to access it.
RIP & Multicast Setup
RIP Direction Select the RIP direction from None, Both, In Only and Out Only.
RIP Version Select the RIP version from RIP-1, RIP-2B and RIP-2M.
Multicast IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a multicast group. The ZyXEL Device supports both
IGMP version 1 (IGMP-v1) and IGMP-v2. Select None to disable it.
Windows Networking
(NetBIOS over TCP/IP)
NetBIOS (Network Basic Input/Output System) are TCP or UDP packets that
enable a computer to connect to and communicate with a LAN. For some dial-
up services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls.
However it may sometimes be necessary to allow NetBIOS packets to pass
through to the WAN in order to find a computer on the WAN.
