Configuring Static NAT in Cisco Routers With CLI || CCNA
NAT (Network Address Translation) configuration is important in Cisco routers for several reasons: IP address conservation: NAT allows you to use a private pool of IP addresses for your internal network, while still allowing your devices to access the public internet. This is important because there is a limited supply of public IPv4 addresses, and NAT helps to conserve these addresses. Security: NAT can be used to hide the internal network from the public internet, making it more difficult for attackers to scan or attack your devices. This is because NAT translates the private IP addresses of your devices to public IP addresses before they are sent out to the internet.
Flexibility: NAT can be used to create different types of network configurations, such as VPNs and DMZs. This makes it a versatile tool for network administrators. NAT configuration is a complex topic, and there are many different ways to configure NAT on a Cisco router. However, the basic principles are the same: you need to define the inside and outside interfaces, and you need to create NAT entries that map private IP addresses to public IP addresses.
