DESCRIPTION

LAN TCP/IP

 

 

 

IP Address

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

 

factory default. Alternatively, click the right mouse button to copy and/or paste the

 

IP address.

 

 

IP Subnet Mask

The subnet mask specifies the network number portion of an IP address. Your

 

ZyWALL automatically calculates 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, RFC1058 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.

 

 

RIP Version

The RIP Version field controls the format and the broadcasting method of the RIP

 

packets that the ZyWALL 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-2Band RIP-2Msends the routing data in RIP-2 format; the difference being

 

that RIP-2Buses subnet broadcasting while RIP-2Muses 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 the Version set to

 

RIP-1.
