Configuring NAT
4
Associating a range of private addresses with a pool and enabling PAT
Use ip nat inside source list to associate a private address range with a pool of Internet addresses
and enable PAT. For an example, refer to
“Dynamic NAT configuration example 1” on page 62.
Syntax: [no] ip nat inside source list acl-id pool pool-name
The inside source keyword specifies that the translation applies to private addresses sending
traffic to the Internet (inside source).
The list acl-id parameter specifies a standard or extended ACL. Named ACLS are not supported with
NAT. You must use a numbered ACL.
The pool pool-name parameter specifies the pool name. You must create the pool before you can
use it with this command.
NAT configuration examples
The following sections provide both Dynamic and Static NAT configuration examples.
NOTE
A Brocade Virtual ADX can have a maximum of 255 global IP addresses, in a single pool or multiple
pools.
Dynamic NAT configuration example 1
This section describes the Dynamic NAT configuration shown in Figure 3 .
FIGURE 3 Minimum required commands
Figure 3 shows an example of a network using dynamic NAT on a Brocade Virtual ADX. The device is
acting as a gateway to connect a private network to the Internet. The private network, which can
also be considered as the inside network, is using IP addresses in the range of 10.10.1.2 -
10.10.1.254 with a 24-bit subnet mask.
