Table 5-1 IP
LABEL DESCRIPTION
Pool Size This field specifies the size or count of the IP address pool.
DNS Servers Assigned by DHCP Server
First DNS Server
Second DNS
Server
Third DNS Server
Select From ISP if your ISP dynamically assigns DNS server information (and the
ZyAIR's WAN IP address). The field to the right displays the (read-only) DNS server
IP address that the ISP assigns.
Select User-Defined 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 User-Defined, but leave the
IP address set to 0.0.0.0, User-Defined changes to None after you click Apply. If
you set a second choice to User-Defined, and enter the same IP address, the
second User-Defined changes to None after you click Apply.
Select DNS Relay to have the ZyAIR act as a DNS proxy. The ZyAIR's LAN IP
address displays in the field to the right (read-only). The ZyAIR tells the DHCP
clients on the LAN that the ZyAIR itself is the DNS server. When a computer on the
LAN sends a DNS query to the ZyAIR, the ZyAIR forwards the query to the ZyAIR's
system DNS server (configured in the SYSTEM General screen) and relays the
response back to the computer. You can only select DNS Relay for one of the three
servers; if you select DNS Relay for a second or third DNS server, that choice
changes to None after you click Apply.
Select None if you do not want to configure DNS servers. If you do not configure a
DNS server, you must know the IP address of a machine in order to access it.
LAN TCP/IP
IP Address Type the IP address of your ZyAIR in dotted decimal notation, for example,
192.168.1.1 (factory default).
IP Subnet Mask Type the subnet mask assigned to you by your ISP (if given).
RIP Direction

RIP Version
Select the RIP version from RIP-1, RIP-2B and RIP-2M.
Multicast IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to
establish membership in a multicast group. The ZyAIR supports both IGMP version 1
(IGMP-v1) and IGMP-v2. Select None to disable it.
Windows Networking (NetBIOS over TCP/IP)

LAN and WAN

port.
