DESCRIPTION

Relogin

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

Every(min)

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

(Telia Login only)

between logins.

 

 

WAN IP Address

 

Assignment

 

 

 

Get automatically

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

from ISP

default selection.

 

 

Use Fixed IP

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

Address

 

 

 

My WAN IP

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

Address

 

 

 

My WAN IP

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

Subnet Mask

Fixed IP Address.

Gateway IP

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

Address

Use Fixed IP Address.

 

 

Advanced Setup

 

 

 

Enable NAT

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

(Network

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

Address

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

Translation)

public IP address used on the Internet).

 

Select this check box to enable NAT.

 

 

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-1is universally supported; but RIP-2carries 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-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.
