Chapter 36 WAN and Dial Backup Setup Table 220 Menu 11.3.2: Remote Node Network Layer Options FIELD DESCRIPTION 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 22 on page 435 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. Refer to Section 44.2 on page 675 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 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 Section on page 152 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. 36.3.5 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.
