Zorluk: OrtaInside Source NAT and PAT Configuration and Verification

A network administrator needs to configure a one-to-one static Network Address Translation (NAT) mapping on a Cisco IOS router. The internal host with private IPv4 address 10.1.1.5010.1.1.50 must be statically translated to the public IPv4 address 198.51.100.50198.51.100.50. What exact Cisco IOS global configuration command should be entered to establish this static NAT mapping?

Cevap: ip nat inside source static 10.1.1.50 198.51.100.50 / ip nat inside source static 10.1.1.50 198.51.100.50

Cevap

ip nat inside source static 10.1.1.50 198.51.100.50
The correct command syntax for establishing static NAT in Cisco IOS global configuration mode is `ip nat inside source static <inside-local-ip> <inside-global-ip>`. Substituting 10.1.1.5010.1.1.50 as the inside local IP and 198.51.100.50198.51.100.50 as the inside global IP yields `ip nat inside source static 10.1.1.50 198.51.100.50`.

Adım Adım Çözüm

1
Identify the static NAT command structure in Cisco IOS.
The static NAT syntax is `ip nat inside source static <local-ip> <global-ip>`.
Static NAT maps a specific inside local address to a specific inside global address.
2
Substitute the specified inside local IP address (10.1.1.5010.1.1.50) and inside global IP address (198.51.100.50198.51.100.50) into the command structure.
The complete command becomes `ip nat inside source static 10.1.1.50 198.51.100.50`.
This establishes a permanent one-to-one translation between the private IP address and public IP address.
