STRUCTURE FOR NAT PROCESS
Client on a Private Network Behind a Routing and Remote Access NAT Accessing a Resource over the Internet
| Component | Description |
|---|---|
Client PCs
|
Each client has a private IPv4 address configured on its network adapter. Clients need only a Web browser and access to a NAT-enabled router to be able to access the Web server across the Internet.
|
Routing and Remote Access NAT-enabled router
|
The NAT-enabled router has a private IP v4 address configured on its private interface, and a public IPv4 address configured on its Internet interface (in this example, a dial-up modem). The router has the optional Basic Firewall, DHCP allocator, and DNS proxy NAT components enabled. For more information, see “Optional NAT Subsystems.”
For a larger network, an administrator might also configure a more sophisticated firewall in addition to using Basic Firewall to protect the Internet interface of the NAT-enabled router and might use a DHCP server (required if the network has more than one segment) and a DNS server.

Web server
|
A Web server on the Internet provides resources needed by the client computers on the private network. Like all computers on the Internet, it has a public IPv4 address.
