35.3.5 Editing Login Script
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
Chapter 21 on page 431 for a full discussion on this feature.
