What is NAT?

Network Address Translation (NAT) is a method of remapping one IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. NAT is commonly used to allow multiple devices on a private network to share a single public IP address when communicating with the internet.

What other technologies are related to NAT?

NAT Competitor Technologies

SSL VPN

SSL VPN can provide secure remote access. It can act as a alternative to NAT in some scenarios. SSL VPNs usually involve reverse proxy and may involve NAT. Can be considered a competitor because it's an alternative way to expose services.

NAT Complementary Technologies

IPSEC

IPSec can be used to create secure VPN tunnels that may need to traverse NAT devices. It's often used in conjunction with NAT.

PAT

PAT (Port Address Translation) is a specific type of NAT that uses port numbers to distinguish between different internal hosts. It is a specific implementation of NAT, so it's complementary.

DHCP

DHCP is used to assign IP addresses. NAT often works in conjunction with DHCP, as the NAT device needs to have an address to assign via DHCP.
