ZyWALL 5/35/70 Series User’s Guide

For some remote gateways, text login is required before PPP negotiation is started. The 
ZyWALL provides a script facility for this purpose. The script has six programmable sets; 
each set is composed of an ‘Expect’ string and a ‘Send’ string. After matching a message from 
the server to the ‘Expect’ field, the ZyWALL returns the set’s ‘Send’ string to the server.

For instance, a typical login sequence starts with the server printing a banner, a login prompt 
for you to enter the user name and a password prompt to enter the password:

Welcome to Acme, Inc.

Login: myLogin

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). 
Press [SPACE BAR] and then [ENTER] to select either Full Feature, None or SUA 
Only. 
Choose None to disable NAT.
Choose SUA Only if you have a single public IP address. SUA (Single User Account) is 
a subset of NAT that supports two types of mapping: Many-to-One and Server. 
Choose Full Feature if you have multiple public IP addresses. Full Feature mapping 
types include: One-to-One, Many-to-One (SUA/PAT), Many-to-Many Overload, 
Many- One-to-One and Server. When you select Full Feature you must configure at 
least one address mapping set.
See 

for a full discussion on this feature.

NAT Lookup 
Set

If you select SUA Only in the Network Address Translation field, it displays 255 and 
indicates the SMT will use the pre-configured Set 255 (read only) in menu 15.1.
If you select Full Feature or None in the Network Address Translation field, it 
displays 1, 2 or 3 and indicates the SMT will use the pre-configured Set 1 in menu 15.1 
for the first WAN port,  Set 2 in menu 15.1 for the second WAN port and Set 3 for the 
Backup port.

Metric

Enter a number from 1 to 15 to set this route’s priority among the ZyWALL’s routes. The 
smaller the number, the higher priority the route has.

Private

This parameter determines if the ZyWALL will include the route to this remote node in 
its RIP broadcasts. If set to Yes, this route is kept private and not included in RIP 
broadcasts. If No, the route to this remote node will be propagated to other hosts 
through RIP broadcasts.

RIP Direction Press [SPACE BAR] and then [ENTER] to select the RIP Direction from Both, None, 

In Only, Out Only and None.

Version 

Press [SPACE BAR] and then [ENTER] to select the RIP version from RIP-1, RIP-2B 
and RIP-2M.

Multicast

IGMP (Internet Group Management Protocol) is a session-layer protocol used to 
establish membership in a Multicast group. The ZyWALL supports both IGMP version 1 
(IGMP-v1) and version 2 (IGMP-v2). Press the [SPACE BAR] to enable IP Multicasting 
or select None to disable it. See

 

for more information on this 

feature.
