5.3 DHCP
Setup
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain
TCP/IP configuration at start-up from a server. You can configure the ZyAIR as a DHCP server or disable it.
When configured as a server, the ZyAIR provides the TCP/IP configuration for the clients. If set to None,
DHCP service will be disabled and you must have another DHCP server on your LAN, or else the computer
must be manually configured.

5.4 Factory
LAN
Defaults
The LAN parameters of the ZyAIR are preset in the factory with the following values:
• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
IP Pool Setup
The ZyAIR is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64. This
configuration leaves 31 IP addresses (excluding the ZyAIR itself) in the lower range for other server
computers, for instance, servers for mail, FTP, TFTP, web, etc., that you may have.
These parameters should work for the majority of installations. If your ISP gives you explicit DNS server
address(es), read the embedded web configurator help regarding what fields need to be configured.

5.5 RIP
Setup
RIP (Routing Information Protocol, RFC 1058 and RFC 1389) allows a router to exchange routing
information with other routers. RIP Direction controls the sending and receiving of RIP packets. When set
to:
1. Both - the ZyAIR will broadcast its routing table periodically and incorporate the RIP information that
information with other routers. RIP Direction controls the sending and receiving of RIP packets. When set
to:
1. Both - the ZyAIR will broadcast its routing table periodically and incorporate the RIP information that
it receives.
2. In Only - the ZyAIR will not send any RIP packets but will accept all RIP packets received.
3. Out Only - the ZyAIR will send out RIP packets but will not accept any RIP packets received.
4. None - the ZyAIR will not send any RIP packets and will ignore any RIP packets received.
RIP Version controls the format and the broadcasting method of the RIP packets that the ZyAIR sends (it
recognizes both formats when receiving). RIP-1 is universally supported; but RIP-2 carries more
information. RIP-1 is probably adequate for most networks, unless you have an unusual network topology.
Both RIP-2B and RIP-2M send routing data in RIP-2 format; the difference being that RIP-2B uses subnet
broadcasting while RIP-2M uses multicasting. Multicasting can reduce the load on non-router machines
since they generally do not listen to the RIP multicast address and so will not receive the RIP packets.
However, if one router uses multicasting, then all routers on your network must use multicasting, also.
By default, RIP Direction is set to Both and RIP Version to RIP-1.
