Use the instructions in the following table to configure TCP/IP parameters for the LAN port.
Table 88 Menu 3.2: LAN TCP/IP Setup Fields
FIELD DESCRIPTION
TCP/IP Setup:
IP Address Enter the IP address of your ZyAIR in dotted decimal notation
IP Subnet Mask Your ZyAIR will automatically calculate the subnet mask based on the IP
address that you assign. Unless you are implementing subnetting, use the
subnet mask computed by the ZyAIR.
RIP Direction Press [SPACE BAR] and then [ENTER] to select the RIP direction. Options are:
Both, In Only, Out Only or None.
Version Press [SPACE BAR] and then [ENTER] to select the RIP version. Options are:
RIP-1, RIP-2B or 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 version 2 (IGMP-v2). Press [SPACE BAR] and then
[ENTER] to enable IP Multicasting or select None (default) to disable it.
Edit IP Alias The ZyAIR supports three logical LAN interfaces via its single physical Ethernet
interface with the ZyAIR itself as the gateway for each LAN network. Press
[SPACE BAR] to select Yes and then press [ENTER] to display menu 3.2.1
When you have completed this menu, press [ENTER] at the prompt [Press ENTER to Confirm…] to
save your configuration, or press [ESC] at any time to cancel.
Size of Client IP
Pool
This field specifies the size, or count of the IP address pool.
First DNS Server
Second DNS
Server
Third DNS Server
The ZyAIR passes a DNS (Domain Name System) server IP address (in the order
you specify here) to the DHCP clients.
Select From ISP if your ISP dynamically assigns DNS server information (and the
ZyAIR's WAN IP address). The IP Address field below 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 IP Address field below. If you chose User-Defined, but
leave the IP address set to 0.0.0.0, User-Defined changes to None after you save
your changes. If you set a second choice to User-Defined, and enter the same IP
address, the second User-Defined changes to None after you save your changes.
Select DNS Relay to have the ZyAIR act as a DNS proxy. The ZyAIR's LAN IP
address displays in the IP Address field below (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 menu 1) 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 save your changes.
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.
DHCP Server
Address
If Relay is selected in the DHCP field above, then type the IP address of the actual,
remote DHCP server here.
