Which steps you choose to configure Pat?

To configure PAT, the following commands are required:

  1. configure the router’s inside interface using the ip nat inside command.
  2. configure the router’s outside interface using the ip nat outside command.
  3. configure an access list that includes a list of the inside source addresses that should be translated.

What are two benefits of NAT choose two?

Some benefits of NAT include: Reuse of private IP addresses. Enhancing security for private networks by keeping internal addressing private from the external network. Connecting a large number of hosts to the global Internet using a smaller number of public (external) IP address, thereby conserving IP address space.

What are the two basic types of NAT choose two?

There are 3 types of NAT:

  • Static NAT – In this, a single private IP address is mapped with single Public IP address, i.e., a private IP address is translated to a public IP address. …
  • Dynamic NAT – In this type of NAT, multiple private IP address are mapped to a pool of public IP address . …
  • Port Address Translation (PAT) –

What is primary purpose of Nat?

It enables private IP networks that use unregistered IP addresses to connect to the Internet. NAT operates on a router, usually connecting two networks together, and translates the private (not globally unique) addresses in the internal network into legal addresses, before packets are forwarded to another network.

How do you implement Pat?

To configure PAT, the following commands are required:

  1. Configure the router’s inside interface using the ip nat inside command.
  2. Configure the router’s outside interface using the ip nat outside command.
  3. Configure an access list that includes a list of the inside source addresses that should be translated.

What is Pat in networking with example?

An example of PAT is a home network that is connected to the Internet. Within this setup, the system’s router is assigned a discrete IP address. Multiple users can access the Internet over the router, and are each assigned a port number as they do so.

What is a disadvantage of Nat?

Disadvantage of NAT –

Translation results in switching path delays. Certain applications will not function while NAT is enabled. Complicates tunneling protocols such as IPsec. Also, router being a network layer device, should not tamper with port numbers(transport layer) but it has to do so because of NAT.

Why would a network administrator issue the show CDP Neigbors command on a router?

Under which two circumstances would a router usually be configured as a DHCPv4 client choose two?

Under which two circumstances would a router usually be configured as a DHCPv4 client? It should use the information that is contained in the RA message and contact a DHCPv6 server for additional information. A network administrator configures a router to send RA messages with M flag as 0 and O flag as 1.

What is NAT Type 2?

What is difference between NAT and PAT?

NAT stands for Network Address Translation. PAT stands for Port Address Translation. … In NAT, Private IP addresses are translated into the public IP address. In PAT, Private IP addresses are translated into the public IP address via Port numbers.

What is the most important security advantage to Nat?

The main advantage of NAT (Network Address Translation) is that it can prevent the depletion of IPv4 addresses. NAT (Network Address Translation) can provide an additional layer of security by making the oringinal source and destination addresses hidden.

What is the purpose of port forwarding?

In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.
