Cisco Secure Access Help Secure Access NAT as a Service Web Traffic and NATaaS

Last updated: Aug 07, 2025

Web Traffic and NATaaS

An IP address available from the NATaaS enables you to register your traffic for allow lists maintained by internet sites and services. An IP address available from the NATaaS affects only the source IP for your internet-bound traffic. It does not affect the IP address that you use to establish the IPsec tunnel between your network and Secure Access.

The NATaaS will use an IP address from the shared ranges below. If you connect to websites or SaaS applications that implement IP allow-listing, provide these IP address ranges. If you require a dedicated IP address, see Reserved IP.
