DESCRIPTION
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).
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 16 Network Address Translation (NAT)
feature.
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 the NAT Setup section
more information.
Enter a number from 1 to 15 to set this route's priority among the ZyWALL's routes
(see the TCP/IP Priority (Metric) section
number, the higher priority the route has.
This field is valid only for PPTP/PPPoE encapsulation. 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 broadcast. If No, the route to this
remote node will be propagated to other hosts through RIP broadcasts.
Press [SPACE BAR] and then [ENTER] to select the RIP direction from Both/ None/In
Only/Out Only. See Chapter 4 LAN
for RIP on the WAN side is None. It is recommended that you do not change this
setting.
Press [SPACE BAR] and then [ENTER] to select the RIP version from RIP-1/RIP-2B/
RIP-2M or None.
IGMP (Internet Group Multicast Protocol) is a network-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 [SPACE BAR] to enable IP Multicasting or select
None to disable it. See Chapter 4 LAN Screens
