Configuration Commands
The following commands are provided as an example to further illustrate the recommended
configuration with respect to security. QoS configuration is beyond the scope of this appendix.
These configuration examples are based on the Cisco IOS Firewall feature set. Adtran
®
routers
use a very similar command set called AOS. For more information about Adtran routers Adtran
Netvanta Switch/Router on page B-29. These commands are not intended to be complete; they
are only a guideline.
Private Network With Near-end NAT Traversal
The following diagram shows a configuration example.

Router (for
example,

Configure the NAT device to perform
a static NAT assignment so that a
designated public IP address (for
example 208.13.17.2) always
corresponds to the Inter -Tel CS-5x00
private address (for example ;
192.168.1.2).
The IP endpoint must be
configured to “talk” to the (public)
NAT IP address of the Inter -Tel
CS-5x00 (for example:
208.13.17.2).
IP Endpoint
(Private Address)
The internal IP endpoints talk to
the private (native) address of the
Inter-Tel CS-5x00.
