Secure Access NAT as a Service
Secure Access secure web gateway (SWG) traffic that is bound for internet destinations takes the Secure Access NAT as a Service (NATaaS) as its egress point. NATaaS provides secure, efficient connections to internet destinations. NATaaS assigns public IP addresses to internet-bound traffic from a shared pool of IPv4 and IPv6 addresses, or from a single IPv4 address reserved for each geographic region where your Secure Access organization is deployed.
For more information on reserving your IPv4 address, see Reserved IP.
