Network object NAT rules are added to section 2 of the NAT rules table. For more information about
NAT ordering, see the “NAT Rule Order” section on page32-20.
Licensing Requirements for Network Object NAT
The following table shows the licensing requirements for this feature:
Prerequisites for Network Object NAT
Depending on the configuration, you can configure the mapped address inline if desired or you can create
a separate network object or network object group for the mapped address. Network object groups are
particularly useful for creating a mapped address pool with discontinous IP address ranges or multiple
hosts or subnets. To create a network object or group, see the “Configuring Network Objects and
Groups” section on page20-1.
For specific guidelines for objects and groups, see the configuration section for the NAT type you want
to configure. See also the “Guidelines and Limitations” section.
Guidelines and Limitations
Context Mode Guidelines
Supported in single and multiple context mode.
Firewall Mode Guidelines
•Supported in routed and transparent firewall mode.
•In transparent mode, you must specify the real and mapped interfaces; you cannot use --Any--.
•In transparent mode, you cannot configure interface PAT, because the transparent mode interfaces
do not have IP addresses. You also cannot use the management IP address as a mapped address.
IPv6 Guidelines
Does not support IPv6.
Additional Guidelines
•You can only define a single NAT rule for a given object; if you want to configure multiple NAT
rules for an object, you need to create multiple objects with different names that specify the same
IP address, for example, object network obj-10.10.10.1-01, object network obj-10.10.10.1-02,
and so on.
