Paradyne 9126, 9126-II, 9128-II, CSU, DSU NAT and NAPT Configuration Example

5. Configuring the FrameSaver SLV Router
5-10 September 2002 9128-A2-GB20-80
NAT and NAPT Configuration Example
The router can be configured for NAT and NAPT simultaneously.
In this NAT and NAPT example:
Multiple workstations in the private address space can use NAPT, and the
server in the private address space can use NAT.
The server may need NAT to send more than TCP/UDP traffic, or
accommodate multiple types of inbound traffic types.
For example, a Web server that uses FTP for maintenance needs access from
the public address side for HTTP and FTP using NAT.
Procedure
To configure the router for both NAPT and NAT:
1. Set up the router for NAPT. See
Network Address Port Translation
on
page 5-8.
2. Set up a static address for any host not using NAPT:
ip nat inside source static 10.1.1.1 155.22.17.1
