NAT and NAPT Configuration Example
The router can be configured for NAT and NAPT simultaneously.
In this NAT and NAPT example:
T
Multiple workstations in the private address space can use NAPT, and the
server in the private address space can use NAT.
T
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
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
