Learning Network 12--static NAT via Cisco emulator Cisco PACKET Tracer

Nat[network address translation] In the absence of IP address in the case of a great use, it can not be normal Sisu network of the intranet address into a legitimate external network address on the public network to send and receive data. At the same time address translation function can also be very good to hide and protect the host network.

Nat has static NAT (internal address and external address one-to-one) and dynamic NAT (internal address pool and external address Pool A-do)

This time we'll look at static NAT

Configuration ideas

1 Configuring the interface address for Router 1 and Router 2

2 Configure the address of the PC and the server, the gateway is the address of the corresponding router Xia Lian interface

3 Configure static routes so that networks can communicate with each other

4 Configure NAT option on Router 1 port and configure static NAT in global configuration mode

Network topology

1 Configure two port addresses for Router 1 and enable ports

2 Configure each interface address of Router 2 and open the port

3 Configuring the server and PC1 addresses

4 Configuring static routes so that networks can communicate with each other

5 Configure NAT option on Router 1 port and configure static NAT in global configuration mode
