Set

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

Refer to Section 38.2 on page 597 for more information.

 

 

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 Multicast 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 Section 6.5 on page 149 for more information on this

 

feature.

 

 

Once you have completed filling in Menu 11.3.2 Remote Node Network Layer Options, press [ENTER] at the message “Press ENTER to Confirm...” to save your configuration and return to menu 11.3, or press [ESC] at any time to cancel.

30.3.5 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

Password:

To handle the first prompt, you specify “ogin: ” as the ‘Expect’ string and “myLogin” as the ‘Send’ string in set 1. The reason for leaving out the leading “L” is to avoid having to know exactly whether it is upper or lower case. Similarly, you specify “word: ” as the ‘Expect’ string and your password as the ‘Send’ string for the second prompt in set 2.

You can use two variables, $USERNAME and $PASSWORD (all UPPER case), to represent the actual user name and password in the script, so they will not show in the clear. They are replaced with the outgoing login name and password in the remote node when the ZyWALL sees them in a ‘Send’ string. Please note that both variables must been entered exactly as shown. No other characters may appear before or after, either, i.e., they must be used alone in response to login and password prompts.
