Provides an overview of Network Infrastructure in Cisco Secure Access, including Manage Network Devices, Secure Access NAT as a Service, and Network Connections. It outlines the concepts, configuration tasks, and operational guidance presented in this chapter.
Manage Network Devices
Describes Manage Network Devices in Cisco Secure Access. In Cisco Secure Access, you can add a hardware or virtual network device—for example, a router, switch, access point, or firewall—that routes DNS traffic to Secure Access's recursive DNS servers.
Secure Access NAT as a Service
Secure Access NAT as a Services (NATaaS) provides secure, efficient connections to internet destinations through assignments of public IP addresses to internet-bound traffic.
Network Connections
Understand the network connections that Secure Access supports to direct traffic to internet and private resources.
Network Tunnel Groups
Network tunnel groups organize IPsec tunnels from supported network devices so traffic can connect securely to Secure Access through shared regional hubs. They provide redundant, highly available tunnel connectivity by pairing tunnels with primary and secondary data center hubs that can be monitored and managed as a group.
Routing Options and Guidelines for Network Tunnel Groups
Before you configure network tunnel groups in Secure Access, understand and choose the correct routing option for tunnel redundancy and high availability.
