NAT Settings Tab

Use the NAT Settings tab of the VPN Global Settings page to define the NAT settings that will be configured on the devices in your VPN topology.

Note If you want to bypass NAT configuration on IOS routers, make sure the Do Not Translate VPN Traffic check box is selected in the NAT Dynamic Rule platform policy (see NAT Dynamic Rule Dialog Box, page C-503). To exclude NAT on PIX Firewalls or ASA devices, make sure this check box is selected in the NAT Translation Options platform policy (see Translation Options Page, page C-231).

For more information about NAT, see Understanding NAT, page 9-70.
