Configuring Network Address Translation (NAT)
Configuring NAT
Figure 8-17. Add Static Translation Screen
3. In the NAT section, select the Interface Type and Address Type:
a. The Interface Type determines to which interfaces the Wireless Edge
Services xl Module applies the static NAT definition:
– Outside (Public)—incoming traffic on an outside interface
– Inside (Private)—incoming traffic on an inside interface
b. For the Address Type, select Source—The module translates the
packet’s source IP address.
The correct settings depend, of course, on the goal of the NAT configura-
tion and on how you have defined interfaces in your network.
When you select Source for the Address Type, the Interface Type choice is
relatively straightforward: choose Inside (Private) to apply NAT to inside
devices and Outside (Public) to apply NAT to outside devices.
See the “Static, or One-to-One, NAT” on page 8-8 and “Planning the NAT
Configuration” on page 8-14 for more guidelines on choosing these
settings.
4. In the Before Translation section, specify the IP address of traffic to which
the module should apply NAT.
a. In the Local Address field, enter the IP address to be translated.
This address depends on the choices that you made in the NAT section.
Refer to Table 8-5.
