Chapter 5 WAN Screens

Relogin

Every(min)

(Telia Login only)

The Telia server logs the ZyWALL out if the ZyWALL does not log in periodically.

Type the number of minutes from 1 to 59 (30 default) for the ZyWALL to wait

between logins.

WAN IP Address

Assignment

Get automatically

from ISP

Select this option If your ISP did not assign you a fixed IP address. This is the

default selection.

Use Fixed IP

Address

Select this option If the ISP assigned a fixed IP address.

My WAN IP

Address

Enter your WAN IP address in this field if you selected Use Fixed IP Address.

My WAN IP

Subnet Mask

Enter the IP subnet mask (if your ISP gave you one) in this field if you selected Use

Fixed IP Address.

Gateway IP

Address

Enter the gateway IP address (if your ISP gave you one) in this field if you selected

Use Fixed IP Address.

Advanced Setup

Enable NAT

(Network Address

Translation)

Network Address Translation (NAT) allows the translation of an Internet protocol

address used within one network (for example a private IP address used in a local

network) to a different IP address known within another network (for example a

public IP address used on the Internet).
Select this checkbox to enable NAT.
For more information about NAT see

Chapter 11 on page 177

RIP Direction

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.
Choose Both, None, In Only or Out Only.
When set to Both or Out Only, the ZyWALL will broadcast its routing table

periodically.
When set to Both or In Only, the ZyWALL will incorporate RIP information that it

receives.
When set to None, the ZyWALL will not send any RIP packets and will ignore any

RIP packets received.
By default, RIP Direction is set to Both.

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).
Choose RIP-1, RIP-2B or RIP-2M.
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. 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, the RIP Version field is set to RIP-1.

Enable Multicast

Select this check box to turn on IGMP (Internet Group Multicast Protocol). IGMP is

a network-layer protocol used to establish membership in a Multicast group - it is

not used to carry user data.
