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.

 

 

 

 

 

 

IP Pool Starting

This field specifies the first of the contiguous addresses in the IP address pool. The

 

 

Address

default is 192.168.1.33.

 

 

 

 

 

 

Pool Size

This field specifies the size, or count, of the IP address pool. The default is 32.

 

 

 

 

 

 

Primary/Secondary

Enter the IP addresses of the DNS servers. The DNS servers are passed to the

 

 

DNS Servers

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.

 

 

LAN TCP/IP

 

 

 

 

 

 

 

IP Address

Type the IP address of your ZyWALL in dotted decimal notation. 192.168.1.1 is the

 

 

 

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.
