How does NAT provide security for internal IP addresses?

The NAT router looks at the address translation table and determines that the destination address is in there, mapped to a computer on the stub domain. The NAT router translates the inside global address of the packet to the inside local address, and sends it to the destination computer.

What allows inbound traffic through NAT?

To allow unsolicited inbound traffic (run servers) behind NAT you need to use port mapping/forwarding, which instructs the NAT device to pass all traffic on a certain port to a certain private IP on the LAN side.

How does the NAT router associate the incoming response to packets sent out?

When using NAT, how does the router know which local IP address should receive an incoming packet? Using your example network, suppose computer “A” sends out a packet to someone on the internet. That person then sends back responses for both computer “A” and computer “B” on the same internet IP address.

Does NAT gateway allows inbound traffic?

NAT gateways managed by AWS don’t accept traffic initiated from the internet. However, there are two reasons why information in your VPC Flow Logs might appear to indicate that inbound traffic is accepted from the internet.

What technique allows for inbound traffic through a NAT quizlet?

Port forwarding ; Port forwarding is a technique that allows for inbound traffic through a router configured to NAT.

What is NAT routing?

Network address translation (NAT) is a method of mapping an 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. One Internet-routable IP address of a NAT gateway can be used for an entire private network.

How NAT is helpful to accommodate IPv4 address depletion?

In addition, network address translation (NAT) permits Internet service providers and enterprises to masquerade private network address space with only one publicly routable IPv4 address on the Internet interface of a main Internet router, instead of allocating a public address to each network device.

Which function does NAT perform in a wireless router?

Which function does NAT perform in a wireless router? NAT takes an internal source IP address and translates it to a global IP address. What are three private IPv4 address? (Choose three.)
