Chapter 5 LAN Setup 50
5.4 LAN TCP/IP
The ZyXEL Device has built-in DHCP server capability that assigns IP addresses and DNS
servers to systems that support DHCP client capability.
5.4.1 Factory LAN Defaults
The LAN parameters of the ZyXEL Device 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.
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.
5.4.2 IP Address and Subnet Mask
Refer to Section 3.2 on page 36 in Chapter 3 on page 34 for this information.
5.4.3 RIP Setup
RIP (Routing Information Protocol) allows a router to exchange routing information with
other routers. The RIP Direction field controls the sending and receiving of RIP packets.
When set to:
• Both - the ZyXEL Device will broadcast its routing table periodically and incorporate
the RIP information that it receives.
• In Only - the ZyXEL Device will not send any RIP packets but will accept all RIP
packets received.
• Out Only - the ZyXEL Device will send out RIP packets but will not accept any RIP
packets received.
• None - the ZyXEL Device will not send any RIP packets and will ignore any RIP
packets received.
The Version field controls the format and the broadcasting method of the RIP packets that the
ZyXEL Device 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 sends the routing data in RIP-2 format; the difference being that
RIP-2B uses subnet broadcasting while RIP-2M uses multicasting.
