Software implementations of NAT that are used to provide rem

Software implementations of NAT that are used to provide remote employees access to an organization’s intranet often reduce the network MTU that is reported to local appli- cations. Explain why.

Solution

Dear Student,

Network Address Translation (NAT) is the process where a network device, usually a firewall, assigns a public address to a computer (or group of computers) inside a private network. The main use of NAT is to limit the number of public IP addresses an organization or company must use, for both economy and security purposes.

A maximum transmission unit (MTU) is the largest size packet or frame, specified in octets (eight-bit bytes), that can be sent in a packet- or frame-based network such as the Internet. The Internet\'s Transmission Control Protocol (TCP) uses the MTU to determine the maximum size of each packet in any transmission.

So in your question how software implementation of the NAT reduced the MTU size is because of...

The primary problem with the MTU size being reduced across the network is that some applications may not be able to work well in this environment.So that is why the network MTU is reduced.
