NAT static route intranet to access extranet (Huawei)

1, experiment name: NAT static route internal network access external network (Huawei)

2. The purpose of the experiment is to convert private addresses into legitimate IP addresses, solve the problem of insufficient IP addresses, and effectively avoid * from outside the network. So that the internal network can access the external network, while the external network cannot access the internal network, which plays the role of protecting data in the internal network.

3, Experimental Topology:

① prepares the environment for 2 PCs, 1 switch and 4 routers.

② first configures the PC with IP address and subnet mask and gateway (gateway is configured on router R1 and switch port)

③ configures two different network segments IP;R1- > R2-> R3 on router R1-> R2 ports.

④ is configured to enable static NAT on different network segment ports on R1-> PC

⑤ verification, testing, saving

4. Configuration steps:

Ip 192.168.10.1

Subnet 255.255.255.0

PC2:

Ip192.168.10.2

Subnet 255.255.255.0

Gateway 192.168.10.254

(2) Router:

R1:
