Hello, everyone!
Today, I want to share with you an experiment on static NAT.
I built a simple topology, and now the enterprise intranet needs to be access to Intranet.
Before configuring NAT, I use PC2 to ping PC4 on the Internet:
The result shows that the network between PC2 and PC4 is disconnected. In other words, PCs in the enterprise intranet cannot access Intranet. What should we do?
As mentioned in the previous article, the ISP has given the enterprise two public network addresses 12.x.x.2 and 12.x.x.3. We need to configure static NAT on the edge router AR1 of the enterprise.
Map the private IP address 192.168.0.2 of Server2 to the public IP address 12.x.x.2.
Map the private address 192.168.0.3 of PC2 to the public address 12.x.x.3.
We can configure the device in the interface view or in the global view.
Configure static NAT in the interface view.
Configure static NAT in the system view.
After the configuration is complete, we can run the display nat static command to query the configured static NAT.
Then, ping the terminal on the enterprise network and the terminal on the Internet.
Ping Server2 and PC4.
Ping PC2 and PC4.
Ping PC3 and PC4.
The IP address of PC1 and Server2 have been configured with static NAT on the edge router AR1 of the enterprise. However, static NAT is not configured for the IP address of the PC. Therefore, PC1 and Server2 can access the Internet, but PC3 cannot access the Internet.

Thank you so much for reading and hope it helps you.
