(all have masks of 255.255.255.255)

(#) Part of the "NAT INTERNAL RANGE"

($) One of the "NAT Router" IP Port addresses

(%) Part of a 1 to 1 translation pair in "NAT Map Database"

() Ports are defined for this part of the 1 to 1 translation pair

(@) Part of the "NAT EXTERNAL RANGE"

(*) Part of the "NAT PASSTHRU RANGE"

The IP Mask column is the hexadecimal representation of the mask associated with each
address.

The Flags column is the summation of all flags that apply to each IP address in the NAT
Address Database. The flags are defined briefly in the Flag Legend at the end of the display
and each and is important for NAT functionality. Detailed descriptions of each flag will not
be presented here.

CONFIGURATION SECTION

The next two sections show an example of configuring a Compatible Systems MicroRouter
2220R router to perform Network Address Translation. They also give more detailed
description of the NAT functionality in Compatible Systems routers.

The agreement of the [NAT Global] configuration and [IP <Section ID>] configuration on the
router ports is the most important aspect of NAT functionality in Compatible Systems routers.
The [NAT Global] configuration will be described first, followed by the required parts of the
[IP <Section ID>] configuration for proper NAT functionality.

[ NAT Global ]

The [NAT Global] variables are configured in the same way as other global sections in the
router. The displayed messages are much the same as for all the other sections.
