Cisco Secure Access Help Secure Access NAT as a Service Reserved IP

Last updated: Aug 07, 2025

Reserved IP

A reserved IP is a single-tenant public IP address deployed on Cisco Secure Access. The reserved IP maps to a unique source IP address for your organization's web traffic and is not shared with any other Secure Access instance. Secure Access NAT as a Service (NATaaS) manages the web traffic egressing from the secure web gateway on your reserved IP.

Note:

  • Reserved IP is available only for web traffic protected by the Secure Access secure web gateway.
  • Reserved IP is available only for IPv4.
  • Reserved IP is limited to one for each geographic region deployed for a Secure Access organization. For more information, see Secure Access Regions.
  • Reserved IP is not supported for Intelligent Proxy traffic.
