Zorluk: OrtaNAT and PAT Implementation

Match each Network Address Translation (NAT) term or implementation type on the left to its corresponding functional description on the right.

  • Inside Local AddressThe private IP address configured on an internal host before translation occurs.
  • Inside Global AddressThe publicly routable IP address that represents an internal host to external networks.
  • Port Address Translation (PAT)Maps multiple internal private IP addresses to a single public IP address using unique source ports.
  • Static NATProvides a consistent, permanent one-to-one mapping between a specific internal IP and a public IP address.

Cevap

Inside Local Address matches the private IP configured on an internal host. Inside Global Address matches the public IP representing the host externally. Port Address Translation (PAT) matches mapping multiple internal IPs to one public IP using source ports. Static NAT matches a permanent one-to-one mapping between an internal private IP and a public IP.
Inside Local Address refers to the private IP assigned to a local network node. Inside Global Address refers to the public IP representing an internal host on public networks. Port Address Translation (PAT) multiplexes multiple private IP addresses onto a single public IP address using distinct Layer 4 source port numbers. Static NAT establishes a fixed one-to-one translation between a specific private IP address and a public IP address.

Adım Adım Çözüm

1
Define the internal and external address perspectives defined in Network Address Translation terminology.
Inside Local is the actual private address on the endpoint, whereas Inside Global is the translated public address visible on external networks.
Understanding address naming conventions is essential for configuring and analyzing translation tables.
2
Differentiate between one-to-one translation (Static NAT) and many-to-one translation (PAT).
Static NAT maps one private IP to one public IP permanently, while PAT overloads a single public IP by tracking TCP/UDP port numbers for multiple internal hosts simultaneously.
Different operational requirements dictate whether port multiplexing or static address assignment is appropriate.
