IP Address Management

Network Address Translation (NAT) for a LAN

3-28 Preliminary January 30, 1998 Pipeline User’s Guide

Optionally set Reuse last addr to Yes to continue to use a dynamically

assigned IP address. The Reuse addr timeout value specifies the time to use

the address. Set it to a number of minutes (up to 1440). Limitations apply,

which are described in the Reference Guide.

Exit and save the profile.

Note:

If you have additional routers on your local area network, open Ethernet >

Mod Config > Ether Options, and set the value of Ignore Def Rt to Yes. This

avoids the possibility that a default route from the ISP will overwrite the NAT

route.

NAT for Frame Relay

The single-IP address implementation of NAT extends to Frame Relay.

Connections using Frame Relay encapsulation to the Pipeline running single-IP

address NAT, translate the local addresses into a single, official address set by the

FR address parameter.

Set the Routing parameter in the NAT profile to enable NAT. Set the Lan

parameter to Single IP addr.

When Routing=Yes and a valid, official IP address is entered for FR address,

NAT is enabled for Frame Relay connections.
