LABEL DESCRIPTION
DHCP Server
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients (workstations) to obtain TCP/IP configuration at startup from a
server. Unless you are instructed by your ISP, leave the DHCP Server check box
selected. Clear it to disable the ZyWALL acting as a DHCP server. When
configured as a server, the ZyWALL provides TCP/IP configuration for the clients. If
not, DHCP service is disabled and you must have another DHCP server on your
LAN, or else the workstation must be manually configured. When set as a server,
fill in the following four fields.

DNS Servers
Enter the IP addresses of the DNS servers. The DNS servers are passed to the
DHCP clients along with the IP address and the subnet mask. Leave these entries
at 0.0.0.0 if they are provided by a WAN DHCP server.

IP Address
Type the IP address of your ZyWALL in dotted decimal notation. 192.168.1.1 is the
factory default.
factory default.
IP Subnet Mask
The subnet mask specifies the network number portion of an IP address. Your
ZyWALL 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 ZyWALL.

RIP Direction
RIP (Routing Information Protocol, RFC 1058 and RFC 1389) allows a router to
exchange routing information with other routers. The RIP Direction field controls
the sending and receiving of RIP packets. Select the RIP direction from Both/In
Only/Out Only/None. When set to Both or Out Only, the ZyWALL will broadcast
its routing table periodically. When set to Both or In Only, it will incorporate the RIP
information that it receives; when set to None, it will not send any RIP packets and
will ignore any RIP packets received. Both is the default.
