SOLUTION

Transport mode and tunnel mode are two modes used in IPsec (Internet Protocol Security) to protect IP communications over the Internet.

Advantages of transport mode:

• It provides encryption and authentication of the data payload only, leaving the original IP header intact.
• It is more efficient in terms of processing overhead and bandwidth usage since it only encrypts the data payload.

Disadvantages of transport mode:

• It does not protect the IP header, which can be a potential security risk.
• It may not work for all types of traffic, such as multicast traffic.

Advantages of tunnel mode:

• It encrypts the entire original IP packet, including the IP header, providing end-to-end security.
• It can work for all types of traffic, including multicast traffic.

Disadvantages of tunnel mode:

• It requires more processing overhead and bandwidth usage than transport mode since it encrypts the entire IP packet.
• It may cause some problems with network address translation (NAT) traversal.

Example of when to use transport mode:

• When you want to protect the communication between two hosts on a LAN, but not the entire IP network.

Example of when to use tunnel mode:

• When you want to provide secure communication between two remote networks over the Internet.
