Def Server=N/A
Reuse last addr=N/A
Reuse addr timeout=N/A
2
Enable NAT by setting Routing to Yes. Without this setting, no other setting
is valid.
3
Set Profile to the name of a Connection profile you want to use to connect to
the Network Access Server (NAS).
4
The Lan parameter can be set to Single IP Addr (by default) or to Multiple.
5
FR address refers to Frame Relay. Refer to “NAT for Frame Relay” on page
3-28 for more information.
6
The Static Mappings menu includes 10 Static Mapping nn submenus, where
nn is a value from 01 to 10. Each of these submenus contains parameters for
controlling the translation of the private IP addresses to TCP or UDP port
numbers when operating in single-address NAT mode. You only need to
specify static mappings for connections initiated by devices calling into the
private LAN. For sessions initiated by hosts on the private LAN, the Pipeline
generates a mapping dynamically if one does not already exist in the Static
Mappings parameters.
Each Static Mapping nn menu contains the following parameters:
20-A00 NAT
Static Mapping 01
Valid=Yes
Dst Port#=21
Protocol=TCP
Loc Port#=21
Loc Adrs=181.100.100.102
See “Routing incoming sessions for up to 10 servers on a LAN” on page 3-
30 for information about how to set each parameter.
7
Optionally set Def Server to the IP address of a local server to which the
Pipeline routes incoming packets that are not routed to a specific server and
port. (See “Routing all incoming sessions to the default server” on page 3-29
for more information.)
